The correct answer is A. Tin and Lead.
Fuse wire is a thin wire that is used to protect electrical circuits from damage caused by excessive current. It is made of an alloy of tin and lead because this alloy has a low melting point. When too much current flows through the fuse wire, it melts and breaks the circuit, preventing damage to the other components in the circuit.
Tin is a soft, silvery-white metal that is easily melted. It is often used in alloys with other metals to make them more malleable and less likely to corrode. Lead is a heavy, soft, and malleable metal that is also easily melted. It is often used in alloys with other metals to make them more durable and less likely to break.
The alloy of tin and lead is used in fuse wire because it has a low melting point. This means that it will melt and break the circuit at a lower temperature than other metals, which helps to protect the other components in the circuit from damage.
The other options are incorrect because they are not alloys of tin and lead. Option B, tin and copper, is an alloy that is used to make solder. Option C, lead and copper, is an alloy that is used to make pipes. Option D, copper and silver, is an alloy that is used to make jewelry.
