Solution

The correct option is C Assertion is correct but Reason is incorrect
The surface area of cells determines the exchange of materials. The increase in the volume of the cell increases its metabolic activity.
However, the surface area does not increase correspondingly with the volume. Therefore, larger cells are less efficient.
The surface to volume ratio decreases with the increase in cell size. All passive cells like eggs are, therefore, larger in size.

Thus, the correct answer is option C.
