Explanation

Ground loop (B) refers to a circuit condition where two parallel conductive paths connect to two different grounding reference points - because those points are rarely at exactly the same potential, a small voltage difference drives unwanted current through the loop, causing interference or noise. The other options name real electrical phenomena but describe fundamentally different things: a resistive loop (A) would imply the defining characteristic is resistance, which isn't what this term targets; a capacitive loop (C) implies energy storage via an electric field; an inductive loop (D) refers to a coil or magnetic-field-based sensor/detector (like those used in traffic lights); and a conductive loop (E) is a generic descriptor, not a defined technical term for this specific problem. Memory tip: think "ground loop" - the unwanted path loops between two grounds that should be equal but aren't, creating a circuit where none was intended.
