Answer:
The correct answer is metaphase.
Explanation:
During metaphase, the lining up of the chromosomes takes place at the metaphase plate, under the influence of the mitotic spindle. In each of the chromosomes, the sister chromatids are held together with the help of microtubules from the contrary spindle poles.
In metaphase, the spindle has captivated all the chromosomes and aligned them in the center of the cell, which is ready to differentiate.
