The correct answer is C. Nichrome.
Nichrome is an alloy of nickel and chromium, with small amounts of iron, manganese, and silicon. It is a very strong and durable alloy that is resistant to corrosion and oxidation. It is also a good conductor of electricity, which makes it ideal for use in heating elements.
Solder is an alloy of tin and lead that is used to join metal objects together. It is a soft alloy that melts at a low temperature, making it easy to use. However, solder is not very strong and is
not resistant to corrosion.Alloy steel is a type of steel that is made by combining iron with other metals, such as chromium, nickel, or manganese. Alloy steels are stronger and more durable than regular steel, but they are also more expensive.
German silver is an alloy of copper, nickel, and zinc. It is a white alloy that is often used in jewelry and other decorative items. German silver is not a good conductor of electricity, so it is not suitable for use in heating elements.
