The surface area of cells determines the exchange of materials. The increase in the volume of the cell increases its metabolic activity. However, surface area does not increase correspondingly with the volume. Therefore, larger cells are less efficient. Metabolically active cells are usually small with the higher surface area with per unit volume.
So, the correct answer is option C.
