NEET 2020 Physics Logic Gates MCQ Question
Type: MCQ-conceptual-Medium-Class 12
For the logic circuit shown, the truth table is:
A
A B Y 0 0 1 0 1 1 1 0 1 1 1 0
B
A B Y 0 0 1 0 1 0 1 0 1 1 1 0
C
A B Y 0 0 0 0 1 0 1 0 0 1 1 1
D
A B Y 0 0 0 0 1 1 1 0 1 1 1 1
Correct Answer
Option C
Detailed Explanation
Option C represents a truth table for a logical AND gate. In this configuration, the output Y is only true (1) when both inputs A and B are true (1), which corresponds to the row where both A and B are 1. For all other combinations of A and B (0,0), (0,1), and (1,0), the output Y is false (0), confirming that the circuit behaves as an AND gate.
