Solution

The correct option is A Metaphase
The number of chromosomes is best counted during metaphase. In metaphase, the centromeres of the chromosomes convene themselves on the metaphase plate an imaginary line that is equidistant from the two centrosome poles. This even alignment is due to the counterbalance of the pulling powers generated by the opposing kinetochore microtubules, analogous to a tug-of-war between two people of equal strength.
So, the correct answer is option B.
