Solution

The correct option is B
Secondary Coil

The production of an electromotive force in a circuit by a change in the current in an adjacent circuit which is linked to the first by the flux lines of the magnetic field is called mutual induction.This phenomenon needs two coils. Hence the name primary and Secondary coil.
