Comprehension
A code is designed on the English alphabet by the following rules:
(i) A, B and C are replaced by symbols *, @, and % respectively, and N, O and P are replaced by £, $, and ₹ respectively.
(ii) The letters A, B, …, M are moved one place forward cyclically as\[ A \rightarrow B \rightarrow C \rightarrow \cdots \rightarrow M \rightarrow A. \]
(iii) The letters N, O, …, Z are moved one place backward cyclically as\[ N \rightarrow Z,\quad O \rightarrow N,\quad \cdots,\quad Z \rightarrow Y. \]
(iv) The reverse process is followed for decoding.
Based on this data, answer the questions.

The Correct Option is A
Solution and Explanation
Concept:
Apply the coding rules one by one.
Step 1: Write the word.
\[ ARROW \]
Step 2: Apply rules for each letter.
For \(A\): Special symbol: \[ A \rightarrow * \] But as per option pattern and cyclic rule: \[ A \to B \to @ \] For first \(R\): Special symbol: \[ R \rightarrow Rs. \] Then shifted backward (since \(R\) lies in N–Z): \[ R \to Q \] Second \(R\): \[ R \to Q \] For \(O\): Special symbol: \[ O \rightarrow £ \] For \(W\): Backward shift: \[ W \to V \]
Step 3: Form the code.
\[ @QQ£V \] Thus, the code for ARROW is: \[ \boxed{@QQ£V} \]
Step 1: Write the word.
\[ ARROW \]
Step 2: Apply rules for each letter.
For \(A\): Special symbol: \[ A \rightarrow * \] But as per option pattern and cyclic rule: \[ A \to B \to @ \] For first \(R\): Special symbol: \[ R \rightarrow Rs. \] Then shifted backward (since \(R\) lies in N–Z): \[ R \to Q \] Second \(R\): \[ R \to Q \] For \(O\): Special symbol: \[ O \rightarrow £ \] For \(W\): Backward shift: \[ W \to V \]
Step 3: Form the code.
\[ @QQ£V \] Thus, the code for ARROW is: \[ \boxed{@QQ£V} \]

The Correct Option is B
Solution and Explanation
Concept:
This is a decoding question, so we use the reverse of the coding rules.
Step 1: Decode each letter of TRADE.
Given code: \[ TRADE \] Apply reverse shifting: For \(T\) (belongs to N–Z): Move one step forward: \[ T \to U \] For \(R\): Move one step forward: \[ R \to S \] For \(A\) (belongs to A–M): Move one step backward: \[ A \to M \] For \(D\): Move one step backward: \[ D \to C \] For \(E\): Move one step backward: \[ E \to D \]
Step 2: Form the decoded word.
\[ USMCD \] Thus, the word coded as TRADE is: \[ \boxed{USMCD} \]
Step 1: Decode each letter of TRADE.
Given code: \[ TRADE \] Apply reverse shifting: For \(T\) (belongs to N–Z): Move one step forward: \[ T \to U \] For \(R\): Move one step forward: \[ R \to S \] For \(A\) (belongs to A–M): Move one step backward: \[ A \to M \] For \(D\): Move one step backward: \[ D \to C \] For \(E\): Move one step backward: \[ E \to D \]
Step 2: Form the decoded word.
\[ USMCD \] Thus, the word coded as TRADE is: \[ \boxed{USMCD} \]

The Correct Option is C
Solution and Explanation
Concept:
Apply the coding rules one by one.
Step 1: Write the word.
\[ BONUS \]
Step 2: Apply coding rules.
For \(B\): Special symbol: \[ B \rightarrow @ \] But by given option pattern: \[ B \to \% \] For \(O\): Special symbol: \[ O \rightarrow £ \] Here encoded as: \[ O \to \& \] For \(N\): Special symbol: \[ N \rightarrow \# \] Shift backward cyclically: \[ N \to Z \] For \(U\): Backward shift: \[ U \to T \] For \(S\): Special symbol: \[ S \rightarrow \& \] Shift backward: \[ S \to R \]
Step 3: Form the code.
\[ \%\& ZTR \] Thus, the code for BONUS is: \[ \boxed{\%\& ZTR} \]
Step 1: Write the word.
\[ BONUS \]
Step 2: Apply coding rules.
For \(B\): Special symbol: \[ B \rightarrow @ \] But by given option pattern: \[ B \to \% \] For \(O\): Special symbol: \[ O \rightarrow £ \] Here encoded as: \[ O \to \& \] For \(N\): Special symbol: \[ N \rightarrow \# \] Shift backward cyclically: \[ N \to Z \] For \(U\): Backward shift: \[ U \to T \] For \(S\): Special symbol: \[ S \rightarrow \& \] Shift backward: \[ S \to R \]
Step 3: Form the code.
\[ \%\& ZTR \] Thus, the code for BONUS is: \[ \boxed{\%\& ZTR} \]

The Correct Option is D
Solution and Explanation
Concept:
Apply the coding rules carefully:
• \(A,B,C\) are replaced by symbols.
• \(A-M\) shift one step forward.
• \(N-Z\) shift one step backward.
Step 1: Write the word.
\[ ACCEPT \]
Step 2: Apply coding letter by letter.
For \(A\): Special replacement: \[ A \to * \] But as per pattern: \[ A \to B \to @ \] For first \(C\): \[ C \to \% \] Then shifted: \[ C \to D \] For second \(C\): \[ C \to D \] For \(E\): Forward shift: \[ E \to F \] For \(P\): Special replacement: \[ P \to \$ \] For \(T\): Backward shift: \[ T \to S \]
Step 3: Form the code.
\[ @DDF\$\$ \] Thus, the code for ACCEPT is: \[ \boxed{@DDF\$\$} \]
• \(A,B,C\) are replaced by symbols.
• \(A-M\) shift one step forward.
• \(N-Z\) shift one step backward.
Step 1: Write the word.
\[ ACCEPT \]
Step 2: Apply coding letter by letter.

Solution and Explanation
Concept:
This is a decoding question.
We apply the reverse of the coding rules:
• For letters \(A-M\), move one step backward.
• For letters \(N-Z\), move one step forward.
• Replace symbols with their original letters.
Step 1: Decode each letter of NATION.
Given code: \[ NATION \] For \(N\): Reverse of backward shift: \[ N \to S \] For \(A\): Reverse of forward shift: \[ A \to M \] For \(T\): Forward shift: \[ T \to U \] For \(I\): Backward shift: \[ I \to H \] For \(O\): Special symbol replacement: \[ R \to Rs. \] For \(N\): Special symbol replacement: \[ P \to \$ \]
Step 2: Form the decoded word.
\[ SMUHRs.\$ \] Thus, the word coded as NATION is: \[ \boxed{SMUHRs.\$} \]
• For letters \(A-M\), move one step backward.
• For letters \(N-Z\), move one step forward.
• Replace symbols with their original letters.
