Solution

The correct option is B magnitude
A transformer is a device capable of changing the magnitude of the alternative e.m.f. (voltage) by the changing current flow through its coils. A step-up type of transformer increases the magnitude of the voltage through it, whereas a step-down type decreases the magnitude.
