Solution

The correct option is C
Splitting of the centromeres

Before cell division, each chromosome duplicates to form two identical parts called sister chromatids attached to each other at a region called the centromere. During anaphase, the division of the centromere releases two daughter chromosomes, one for each daughter cell.
