A Correct answer
Explanation

A staircase switch uses two switches to control one light - either switch can toggle it on or off. This matches XOR logic where the output is 1 only when exactly one input is 1. XNOR would require both switches in the same position. OR and NOR do not model the toggling behavior correctly.
