An electric cell works :
(a) as a source of electrons
(b) on deficit of electrons
(c) as a source of protons
(d) none of the above

(a) as a source of electrons

Reason — In an electric cell, excess electrons on the cathode and a deficit of electrons on the anode are maintained by a chemical reaction. This creates a continuous flow of electrons in the external circuit, from the cathode to the anode. Thus, an electric cell works as a source of electrons
