Detailed explanation-1: -A chromatid is one of the two identical halves of a chromosome that has been replicated in preparation for cell division. The two “sister” chromatids are joined at a constricted region of the chromosome called the centromere.

Detailed explanation-2: -At this point, nuclear division begins, and the parent cell is divided in half, forming 2 daughter cells. Each daughter cell will have half of the original 46 chromosomes, or 23 chromosomes. Each chromosome consists of 2 sister chromatids.

Detailed explanation-3: -Each chromosome consists of two units called chromatids.

Detailed explanation-4: -A chromatid refers to one of the two identical halves of a chromosome. After complete cell division, each chromosome contains two sister chromatids.
