Question

Match List-I with List-II.

List-I	List-II
A. AND	I. Output 1 only if both inputs are 1
B. OR	II. Output 1 if any input is 1
C. NAND	III. Output 0 only if both inputs are 1
D. NOR	IV. Output 1 only if both inputs are 0

Choose the correct answer from the options given below:

• A. A-IV, B-III, C-II, D-I
• B. A-I, B-II, C-III, D-IV
• C. A-I, B-III, C-IV, D-II
• D. A-II, B-I, C-IV, D-III

Hint:

NAND = NOT(AND), NOR = NOT(OR).

Answer 1

The Correct Option is B

Concept: Logic gates produce outputs based on input combinations.

Step 1: Match AND gate.
• Output is 1 only when both inputs are 1 \[ A \rightarrow I \]

Step 2: Match OR gate.
• Output is 1 if any one input is 1 \[ B \rightarrow II \]

Step 3: Match NAND gate.
• Complement of AND
• Output is 0 only when both inputs are 1 \[ C \rightarrow III \]

Step 4: Match NOR gate.
• Complement of OR
• Output is 1 only when both inputs are 0 \[ D \rightarrow IV \]

Step 5: Final mapping. \[ A-I,\ B-II,\ C-III,\ D-IV \] \[ \boxed{(2)} \]
