Concept:
This is a letter-coding problem where each letter in the source word follows a specific mathematical pattern to transform into the coded word. Typically, we look for the position of letters in the alphabet (A=1, B=2, ... Z=26).
Step 1: Identify the pattern in the example word.
Let's compare TERROR and SDQQNQ letter by letter:
• T $\rightarrow$ S (T minus 1)
• E $\rightarrow$ D (E minus 1)
• R $\rightarrow$ Q (R minus 1)
• R $\rightarrow$ Q (R minus 1)
• O $\rightarrow$ N (O minus 1)
• R $\rightarrow$ Q (R minus 1)
The pattern is clearly -1 for every single letter.
Step 2: Apply the pattern to the target word REMOVE.
Moving one step back in the alphabet for each letter of REMOVE:
• R - 1 = Q
• E - 1 = D
• M - 1 = L
• O - 1 = N
• V - 1 = U
• E - 1 = D
Step 3: Combine the letters.
The resulting sequence is QDLNUD. Looking at the options:
• Option D matches the result QDLNUD.
Final Answer: Option D
