When the secondary load is overloaded, it draws maximum current in the primary side due to which can damage the primary side as well as appliances. Therefore, primary winding of the power transformer is fused.

The Correct option is D, fused.
When the secondary load is overloaded, it draws maximum current in the primary side due to which damaging the primary side as well as appliances. Therefore primary winding of power transformer is fused. Suppose peak voltage of power source is varying then current will also fluctuate so also to limit the current it is fused.

But we know that we don't use fuse for power t/f we use circuit breakers (switch).

In power transformer primary side low voltage and high current so that's why fuse for protection and fuse is also rating is AMP.

The primary side has too many turns so we use low gage wire, therefore, it delicate than secondary as well as costly.

@Shamraay, you are right.

What is the reason for not using the switching method?

Whenever the t/f is overloaded the overload current is drawn from the primary side to protect the t/f from this over current fuse is used at the primary side of t/f.
So the given answer is correct.
So the given answer is correct.

Fuse required in small primary transformer only upto 11 kv, when we say transformer as a general. The answer shall be closed.
The primary winding shall be closed then only it will work as a transformer and produce flux. SHORTED IS THE ANSWER.
FUSE IN SECONDARY MOSTLY AT 415 V side yes.

Fused for protection purpose.
