The correct answer is A. temperature rise.

A transformer is a device that transfers electrical energy from one circuit to another without a change in frequency. It does this by using electromagnetic induction to create a magnetic field that induces a voltage in a second circuit.

The maximum load that a power transformer can carry is limited by its temperature rise. This is because the transformer’s insulation can only withstand a certain amount of heat before it starts to degrade. If the transformer is overloaded, the temperature of the insulation will rise and it will eventually fail.
