According to the research, the correct option is A. The electrons move back and forth is the statement that is true about AC.
<h3>What is AC?</h3>
It is the flow of electric charges through a conductor is called electric current, if said flow of electric current varies in direction from time to time, we speak of alternating current.
Subatomic particles such as protons and electrons have an electrical charge, a physical property that is manifested by the repulsive and attractive forces that exist between them in AC the electrical charge moves back and forth.
Therefore, we can conclude that according to the research, the correct option is A. The electrons move back and forth is the statement that is true about AC.
