Solution

The correct option is A Both Assertion and Reason are true and Reason is the correct explanation of Assertion
A primary cell is a battery that is designed to be used once and discarded, and not recharged with electricity and reused like a secondary cell (rechargeable battery). In general, the electrochemical reaction occurring in the cell is not reversible, rendering the cell unrechargeable.

A secondary battery is a portable voltaic cell that is rechargeable.

Dry cell is unrechargeable while lead cell is rechargeable. Hence the statement is right.
