A transformer is a device which converts:

ALow voltage at low current into high voltage at high current
BHigh voltage at low current into low voltage at high current
Correct Answer
CHigh voltage at high current into low voltage at low current
DElectrical power into mechanical power

Solution

For a transformer, $$V_pI_p= V_sI_s$$
Hence, it can be used to convert high voltage at low current to low voltage at high current.
