Answer:
The correct answer is - chromosomes align at the spindle equator.
Step-by-step explanation:
Chromosomes move and align at the spindle equator during the metaphase stage of mitosis and other given events take place during the anaphase stage of the mitosis cell division. Metaphase is the second phase of the M-phase of mitosis division whereas anaphase is the third phase.
The metaphase is characterized by the alignment of the chromosomes at the equator whereas the anaphase is separating the chromosomes pulled towards the poles and division of centromeres.
