B. 63% lead and 37% Steal

C. 63% tin and 37% gold

D. 63% lead and 37% aluminum

Fuse wire is made of

Fuse-wire Is formed by tin-lead alloy (63% tin + 37% lead). Therefore, it has a low melting point but high resistivity. It is used in series as a safety device in an electric circuit. And it is designed so as to melt and thereby open the circuit if the current exceeds a decided value due to some fault.
