A) During youthful age, lots of cells undergo mitosis

B) During old age, only few cells undergo mitosis

Explanation:

Mitosis is the division of a cell nucleus in which the genome is copied and separated into two identical halves. It is one of the two types of cell division.

Whenever, a cell undergoes mitosis, there is a slight shortening of the telomeres on the ends of each chromosome. As soon as this shortened telomere reaches a certain length cell division ceases. Then the cell is said to be aged and approaching death phase. These kind of cells is found in adult humans.

On the other hand, cell division occurs faster in babies, as they need to grow to adult size, and that means that their cells must divide faster than adult cells. In fact, depending on the cell type, the infant cells divide as much as twice as quickly as the adult cells.
