Show answer & explanation
Correct answer: C
First, analyze the final NAND gate. For its output Y to be Low (0), both inputs must be High (1). This means input C must be 1, and the output from the NOR gate must also be 1. Next, look at the NOR gate. For a NOR gate to output High (1), all its inputs must be Low (0). Therefore, inputs A and B must both be 0. The required input combination is A=0, B=0, C=1.
