XNOR gate will only output true if both inputs are ______.

The correct choice is that the XNOR gate will only output true if both inputs are the same. An XNOR gate, which stands for "exclusive NOR," is a digital logic gate that provides a true (or high) output when its two inputs are identical. This means that it will output true for the following input combinations: both inputs are true or both inputs are false.

When both inputs are true, the gate outputs true because the condition of sameness is met. Likewise, when both inputs are false, it still meets the condition of sameness and also results in a true output. This property of the XNOR gate makes it useful in applications where equality is needed, such as digital circuits and comparison operations.

In contrast, if the inputs are different in any way—one true and the other false—the output will be false, demonstrating that the XNOR gate only satisifes its output condition with matching inputs. The functionality of the gate emphasizes the concept of equality in binary logic operations.
