Explanation: Primary cells, such as alkaline or carbon-zinc batteries, are engineered for single use. They operate by converting chemical energy into electrical energy through electrochemical reactions that are largely irreversible. * **(B) Cannot be recharged:** During discharge, the active materials within the cell are consumed or undergo permanent chemical changes. These reactions are not designed to be reversed by applying an external charging current. * **(C) An attempt to recharge it would not restore the eroded electrode:** When a primary cell discharges, the electrode materials are consumed, altered, or physically eroded. Applying current in an attempt to recharge would not reverse these fundamental chemical and physical changes, nor would it rebuild the consumed electrode material. It could even lead to dangerous conditions like overheating, leakage, or rupture due to uncontrolled side reactions or gas generation. Therefore, both statements B and C accurately describe the characteristics of primary cells, making (D) the correct and most complete answer. (A) describes secondary (rechargeable) cells, not primary cells.
