Which statement describes two normally open switches in series?

Explanation:
Two normally open switches in series implement an AND condition. Because a normally open switch does not conduct until it is actuated, you must close both switches to complete the circuit. Only when both are actuated does current flow, so the output is true only if both inputs are true. If either switch stays open, the path is broken and no current flows, which matches the AND behavior. This setup wouldn’t produce an OR result (which would require just one closed switch), nor would it produce a NAND or NOR without additional inversion.
