Detailed Solution

Assertion (A) states that mitosis is equational cell division, which means that the daughter cells produced have the same number of chromosomes as the parent cell. This is because during mitosis, the chromosomes replicate and then segregate equally into two daughter cells, resulting in each daughter cell receiving an identical set of chromosomes compared to the parent cell.

Reason (R) supports Assertion (A) by explaining that during mitosis, the daughter cells indeed receive the same number of chromosomes as the parent cell. This consistency in chromosome number is crucial for maintaining the genetic stability of the organism's cells during growth, development, and tissue repair.
