Verified by Toppr

The correct option is C Its colour
A fuse is a safety device that provides overcurrent protection, to an electrical circuit. Its essential component is a metal wire or strip that melts when too much current flows through it, interrupting the current that it connects.
Therefore the working of the fuse depends upon its resistance and current flowing through it.

Hence, the correct option is C.
