In PLR, two inputs connected in series perform which Boolean operation?

Explanation:
Two inputs in series act like a path that only closes when both switches are on. If either input is off, the path is open and no current flows, so the output stays off. That behavior matches the AND operation, where the output is true only when both inputs are true. Wiring inputs in parallel would give OR behavior, while inversion (NOT) or NAND would require additional inversion steps or different wiring.
