Which logic gate outputs 1 if at least one input is 1?

Explanation:
An OR gate outputs a high signal whenever any input is high. For two inputs, the output is 0 only when both inputs are 0; in every other case (one input 1 or both inputs 1), the output is 1. That matches the idea of “at least one input is 1.” The other gates behave differently: AND needs both inputs to be 1, NOR needs both inputs to be 0 to output 1, and XOR outputs 1 only when exactly one input is 1 (not both). So the OR gate is the correct choice.
