NEET 2022 Physics Truth Tables MCQ Question

The question involves analyzing a logic circuit's truth table. In digital logic, a truth table lists all possible input combinations and their corresponding output values. The correct answer, D, indicates that the truth table has 4 unique output combinations. This is typical for a circuit with two binary inputs (A and B), as each input can be either 0 or 1, leading to 2^2 = 4 combinations: (0,0), (0,1), (1,0), and (1,1). Other options (A, B, C) suggest fewer combinations, which would not accurately represent a complete truth table for a two-input logic circuit.
