C Correct answer
Explanation

Nichrome (an alloy of nickel and chromium) is used for heating elements because it has high resistance, high melting point, and doesn't oxidize easily at high temperatures. Pure nickel, chromium, or tungsten don't have the right combination of properties for heating elements.
