Answer 1

The correct option is B use of fuse.

The most important safety method used for protecting home appliances from short-circuiting due to overloading is use of fuse.

The fuse has thin wire of short length made of an alloy of tin/lead.

When the current exceeds a certain limit, the fuse melts and breaks the circuit, thereby protecting home appliances.

​​​​​​​Hence, option $\left(B\right)$ is the correct answer.
