D. Electrons flow because of electrical attraction and repulsion.

Explanation:

Electrical and electronic devices found in homes need electrical energy for their operation. Such energy is obtained when they are plugged into some source of energy, such as a battery or an outlet. When this is done, something invisible happens. Free electrons, which are found in the conducting means of these devices, start to move in an orderly manner, transporting the electrical energy necessary for their operation. This orderly movement of electrons is known as electrical current. When electrical current is dissipated through a wire, electrons flow because of electrical attraction and repulsion.
