What is transformer?

A transformer transfers electric energy from one AC circuit to one or more other circuits, either stepping up or stepping down the voltage.

In step up transformers, the voltage are increased from low to high. Step ups are used of long distance transmission In step down transformers, the voltage is decreased from high to low based on the purpose.

Higher number of coils are used in primary windings than in the secondary coils.

So, higher voltage and and more coils describes the primary winding.

Thus, the correct option is B.
