Correct Answer: melting point
Solution : The correct option is the melting point .
A metal with a low melting point serves as the material for the safety fuse wire found in residential electrical appliances. To create a weak point in the electrical circuit, this is done on purpose. The fuse wire is intended to melt or blow out in the case of a sudden increase in electrical current, such as during a short circuit or overload.
