Solution

The correct option is A thickness of the fuse wire
The maximum current which can flow through a fuse without melting it is called its rating.
For example a fuse rated at 8 A, can stand current upto 8 A. If current higher than 8 A flows through the fuse, it would melt and circuit gets broken.
The rating of a fuse depends upon the thickness of the fuse wire(because length of the wire is fixed).the thicker fuse has higher rating. So, the thickness of the fuse wire in 8 A circuit is more than that of the fuse wire in 5 A circuit.
