Which of the following frequently imposes a limit on cell size?

A) the absence of a nucleus B) the number of mitochondria in the cytoplasm

C) ratios of surface area to volume D) the volume of the endomembrane system

It's option c, ratios of surface area to volume

The correct answer will be option-C.

Explanation:

The ratio of surface area to volume plays an important role in maintaining the size of the cell as the size is related to its function.

If a cell size increases then its volume grows proportionally while the surface area of the cell decreases that is a small cell will have has a greater ratio of the surface area to volume. It also depends on the metabolic requirements of the cell.

Thus, Option-C is the correct answer.
