A) a piece of wire

Explanation:

Radhika's mother is simply replacing piece of wire.

A fuse is made up of a thin strip of wire that melts when there is an over current.

A fuse is electrical safety device in circuit that protects appliances from over current.
The wire in a fuse has a high resistance and low melting point.
When current is high, the resistance of the wire causes it to melt and break the circuit.
In this way, appliances are protected from the harmful effect of the surge in voltage.
