The correct option is C. A transformer is used to convert low a.c. voltage to high voltage and convert high a.c. voltage to low voltage.
Transformers are electrical devices that transfer electrical energy between two or more circuits through electromagnetic induction, typically to change the voltage level. A step-up transformer converts a low AC voltage to a high AC voltage (statement 1), while a step-down transformer converts a high AC voltage to a low AC voltage (statement 2). Transformers only work with alternating current (AC).
