Multiple Choice

A closed, conducting path.

Explanation:
A closed, conducting path defines an electrical circuit. Current can flow only when there’s a complete loop that starts at a power source, travels through conductors (and any components like a lamp or resistor), and returns to the source. The term circuit captures the whole setup—the source, the path, and the load—so it’s more precise than just calling it a loop or a wire. A wire is only a piece of the path, and a loop describes the shape, but the full system that enables current flow is the circuit.
