C Correct answer
Explanation

Nichrome is a nickel-chromium alloy specifically designed for heating elements due to its high electrical resistance and ability to withstand extreme temperatures without oxidizing. It maintains structural integrity even when red-hot, making it ideal for electric heaters, toasters, and hair dryers. The resistance generates heat while the material itself remains stable.
