Show answer & explanation
Correct answer: D
Check outputs for inputs (0,0):
NAND: AND(0,0) = 0 → NAND = 1.
NOR: OR(0,0) = 0 → NOR = 1.
XOR: XOR(0,0) = 0 → XOR = 0.
X-NOR: XNOR is the complement of XOR, so X-NOR(0,0) = 1.
Conclusion: Only the XOR gate does not give output 1 when both inputs are 0. Therefore choose the answer that indicates only the XOR gate.
