A Tin and lead
B Zinc and lead
C Copper and iron
D Carbon and tin

Correct Answer: Tin and lead

An electrical fuse is a safety device in the circuit that protects electrical systems by breaking the connection when a short circuit is occurring. The fuse wire is made up of Sn (tin) and Pb (lead) alloy because of its high resistance and low melting.
