Solution

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion.
Chromosomes are short, thick, condensed rod-like structures present in the nucleus which distribute genetic information to the daughter cells. They are capable of self-replication before the cell division and thus are passed to next generation. They contain genes on them which control the morphological and physiological properties of cells. Thus, the correct answer is option A.
