Answer 2

The right answer to the asked question is Option A.

Fuse is used for protecting the circuit from overload and short circuit.

An electric fuse is a safety instrument, which works on the principle of the heating effect of electrical current. The fuse breaks the circuit when there is an excess flow of current.

If not, then the current flowing through a circuit exceeds its safety limit, then the wires carrying the current get overheated and catch fire leading to a short circuit.
