Hint: In this question, we can identify the correct option on the basis of their definitions and uses. We know that electrical appliances work on a combination of some physical quantities.

Complete step by step solution:
We know that an electrical appliance works by using electric current and voltage. Here, electric current is the moving charge per second and voltage is a type of potential difference which works as a catalyst and makes the charges move. So, in combined form, electrical energy becomes the outcome.
We know that all the electrical appliances use or consume electrical energy so that they can work.
We know that the electrical energy is measured in kWh.
So,
\[
  1kWh = 1kW \times 1h \\
   \Rightarrow 1kWh = 1unit \\
 \]
The electricity bills are calculated on the basis of consumption of electrical energy. We got the amount calculated for the number of units consumed by the appliances.
Hence, electrical energy is consumed using different electrical appliances, for which electricity bills are paid.

Therefore, option B is correct.

Additional Information: Electrical energy is the result of the flow of electrical charge. We know that energy is the ability to do work. In other words, energy is the applied force which gives displacement to an object. In electrical energy this force is either attraction force or repulsion force.

Note: We have to remember the definitions of each given option. We know that each and every appliance needs some type of energy to work. This type of energy depends upon the type of work done. In this question, the work changes into electrical energy. In motion, the work changes into mechanical energy.
