The last option is the correct order of events in mitosis.
Explanation:
The metaphase stage initiated with the arrangement of sister chromatids on the metaphase plate. Post arrangement, the spindle fibers come and combine with the chromatids kinetochore. The cohesion proteins assist in the robust attachment of the spindle fibers and the kinetochore. After the attachment is done, the pulling of sister chromatids takes place towards the pole. The dissociation of cohesion proteins takes place, and the nucleus begins to form again and thus, a novel cell gets formed.
