Solution

The correct option is D Metaphase
Metaphase is the second stage of mitosis— The chromosomes reach their maximum level of condensation. The chromosomes are lined up in the middle of the spindle apparatus. Although the chromatids may be pointing in various directions, the centromeres will be clearly all in a row. So it is easier to count the chromosomes during metaphase than in any other phase.
