Answer: D. Thermal energy

Explanation

A space heater uses resistance elements that are heated by an electrical current.

The thermal energy, Q, generated in a resistance of R ohms that carries a current of I is

Q = I²R

This equation assumes that all the electrical energy is converted into thermal energy without losses.
