Concept:A non-rechargeable cell is a primary cell that cannot be recharged once its chemical energy is used up.Explanation:The dry Leclanché cell is a common primary cell.It uses a zinc anode and a carbon cathode with an ammonium chloride paste.Its chemical reaction is irreversible, so it cannot be recharged.Nickel-iron, mercury-cadmium, and lead-acid cells are all secondary (rechargeable) cells.Therefore, the only non-rechargeable cell among the options is the dry Leclanché cell.Answer:C. dry leclanche
