What is the output of an OR logic gate?

The output of an OR logic gate is 1 if either of its inputs is 1, and it only outputs 0 when both inputs are 0. This means that in any case where at least one of the inputs is true (1), the output will also be true (1). The correct understanding of an OR gate is that its function is to perform a logical disjunction; it validates the presence of truth in either of the input signals.

To clarify, when one input is 1, the OR gate outputs 1 regardless of the state of the other input. Therefore, the output will be 0 only when both inputs are 0, which reaffirms that the correct answer is not C, but rather B. This captures the true operational principle of an OR logic gate.
