Answer:
a) AC voltage
Explanation:
A transformer is a device which step-up or step-down the level of AC current or voltage without changing the primary (i.e. input source) frequency. Transformer only works on AC and can't be operated on DC i.e. it has been designed to be operated only and only on alternating current and voltage.
