Answer 2

The element of the electric device is made up of Nichrome.

• Most of the electrical heating elements use Nichrome 80/20 (80 percent nickel, 20 percent chromium) wire, ribbon, or strip.  

• Nichrome 80/20 percent is an ideal material, as it has comparatively high resistance and makes a supporting layer of CrO when it is heated for the initial time.

•  Solid beneath this layer will not oxidize, stopping the wire from breaking or burning out.

• Hence the correct answer is Nichrome.
