Which gate is represented by the following truth table? A B C | Q 0 0 0 | 1 0 0 1 | 1 0 1 0 | 1 0 1 1 | 1 1 0 0 | 1 1 0 1 | 1 1 1 0 | 1 1 1 1 | 0

Accepted Answer

Correct answer: B — Answer: NAND gate A 3-input NAND gate is the complement of the AND operation. Its output is 0 only when all inputs are 1; otherwise its output is 1. From the truth table: - For 000, 001, 010, 011, 100, 101, and 110, the output Q is 1. - For 111, the output Q is 0. This exactly matches a NAND gate. NOR would be 1 only for 000 and 0 for all other combinations, so NOR is not correct. XOR/XNOR parity patterns also do not match this table.
