The correct answer is C. 1000.
A lead-acid cell is a type of battery that uses lead plates and a sulfuric acid electrolyte to store energy. It is a common type of battery used in cars and other vehicles.
The life of a lead-acid cell is typically measured in the number of charge and discharge cycles it can undergo before it needs to be replaced. The number of cycles a lead-acid cell can withstand depends on a number of factors, including the quality of the battery, the way it is used, and the environment in which it is used.
In general, a lead-acid cell can be expected to last for about 1000 charge and discharge cycles. However, this number can vary depending on the factors mentioned above.
Option A is incorrect because it is too low. A lead-acid cell can typically last for about 1000 charge and discharge cycles.
Option B is incorrect because it is too high. A lead-acid cell can typically last for about 1000 charge and discharge cycles.
Option D is incorrect because it is too high. A lead-acid cell can typically last for about 1000 charge and discharge cycles.
