Solution

The correct option is B Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
The growth of multicellular organisms is due to mitosis. Cell functions are controlled by the nucleus. The size of the nucleus does not change, but cytoplasm increases during cell growth. An increase in size disturbs the nucleocytoplasmic ratio. The ratio is restored to an efficient level through cell division. So, the correct answer is 'B'.
