20 POINTS PLEASE HELP How does the heating element of a portable electric heater work?

A: The element is a switch so some of the electrical energy flowing through the heating element is converted to kinetic energy.

B: The element is a resistor, so some of the electrical energy flowing through the heating element is converted to kinetic energy.

C: The element is a resistor, so some of the electrical energy flowing through the heating element is converted to thermal energy.

D: The element is a switch so some of the electrical energy flowing through the heating element is converted to thermal energy.
