The following truth table represents which logic circuit? A B Y 0 0 1 0 1 1 1 0 1 1 0

Explanation:
This truth table shows Y is high for every input pair except when both A and B are 1. That pattern matches a NAND gate, which outputs the inverse of an AND: Y = NOT(A AND B). So the circuit is NAND. The other gates don’t fit because AND would be high only when both inputs are 1, OR would be high for 01, 10, and 11, and NOR would be high only for 00.
