During mitosis, metaphase differs from anaphase in having

Solution
The correct option is B Half number of chromosomes and same number of chromatids
Metaphase is the second phase of mitosis. In this phase alignment of chromosomes at the metaphase plate is seen in which the chromosomes are aligned in the center of the cell between each of the mitotic spindle poles.In anaphase, the third phase of mitosis, there is a shortening of the spindle microtubules. Each chromosome is pulled along by its centromere the two sister chromatids of each chromosome are pulled apart by the spindle and dragged by their kinetochores toward opposite poles of the cell.
Hence the number of chromosomes is half in metaphase as compared to anaphase but the number of chromatids is the same. Thus the correct answer is option C.
