B.

the total losses depend only on the current

C.

only the iron losses depend on the current

D.

the total losses depend on the voltage and current

Transformer:
It transfers energy from one circuit to another without a change in frequency.
Transformer ratings are expressed in kVA because total losses in transformer are due to the Iron losses depend on the voltage (V) and copper losses depend on the flow of current (A).
