Explanation

The correct option is C 8

In meiosis I, chromosomes in a diploid cell segregate, producing two haploid daughter cells. Each daughter haploid cell will have two chromoatids in each chromsome. Hence, if the mother cell has 8 chromosomes, after meiosis I the progeny cells will have 4 chromosomes. Each chromosome in daughter cells will have two chromatids. So, the required number of chromatids is 4 X 2 = 8.
