Which one of the following logic elements describes a circuit with two normally open switches in series?

Explanation:
Two normally open switches in series act like an AND operation. The circuit only completes and current can flow when both switches are closed, which corresponds to both inputs being true. In logic terms, AND outputs true only when every input is true, so this setup directly maps to that behavior. The other options don’t fit this simple series arrangement. OR would work with a parallel path so that a current can flow if either switch closes. Nand and Nor are inverted forms of AND and OR, respectively, and would require additional logic or inversion to match the two-switch series scenario.
