Show answer and explanation

Correct answer: (b) Fuse

Explanation

A fuse is a safety device that protects appliances and people from excess current and electric shock.

It uses a thin wire of low melting point that melts when current exceeds the safe limit, breaking the circuit.

A generator produces electricity and a motor converts electrical to mechanical energy; neither offers protection.
