Show answer and explanation

Correct answer: (A) Schering bridge

Explanation

Schering bridge compares capacitance and dielectric loss, whereas Maxwell–Wien, Hay and Owen bridges are AC bridge configurations used to determine inductance. Thus A is the bridge outside the inductance-measurement group.
