Best answer
Correct choice is (b) joules (J)

To explain I would say: Electric energy is defined as the total electric work done or energy supplied by the source of emf in maintaining the current in an electric circuit for a given time. The SI unit of electrical energy is joule (J). The commercial unit of electric energy is kilowatt-hour (kWh).
