Why are the conductors of electric heating devices such as bread toasters and electric irons made of an alloy rather than a pure metal?

While alloys are comprised of two or more metals that have been melted together, metals are intrinsic. Because they are typically shinier, heavier, and harder than other materials and because they are efficient conductors of heat and electricity, metals and alloys are simple to differentiate from non-metals.

Because pure metal melts rapidly when the heat is raised and pure metal corrodes easily, electrical heating equipment like toasters and electric irons are built of alloys rather than pure metal. We use alloys rather than pure metal because they do not corrode quickly and have a high melting point.

The alloys provide exceptional fabric ability, superior corrosion resistance, and high strength. The alloy's composition as an electric heating device gives it these advantageous characteristics.

Hence Option C is the correct answer.
