Correct option is A
Nichrome (an alloy of nickel and chromium) is commonly used in heating elements such as those found in electric presses, heaters, and electric kettles. Nichrome is preferred because it has a high melting point, excellent resistance to oxidation, and remains stable at high temperatures. It also has a significant electrical resistance, making it ideal for converting electrical energy into heat efficiently. Nichrome wire is wound into coils and used in appliances that need to generate heat. Other materials, like carbon and constantan, are used in different applications, but nichrome is the most common material for heating elements due to its durability and heat resistance.
