Answer:

B) Low resistivity and low melting point.

Step-by-step explanation:

A fuse is an electric device consisting of an encapsulated lead or tin wire (low resistivity and low melting point) and placed at a point in the electrical circuit to interrupt the current when it is excessive.

When a short circuit occurs ( exists potential difference between the terminals and low impedance), current intensity tends to infinity which jeopardize the connected devices due to the heat generated by the current intensity due to the Joule effect.
