Explanation / Answer

The answer is

B. (1) 120 picograms DNA, 22 chromosomes; (2) 120 picograms DNA, 44 chromosomes; (3) 60 picograms DNA, 22 chromosomes

After S Phase, the DNA replicated and we can find chromatids, but not chromosomes. After chromatid seperation we can call those as chromosomes.
