Solution

The correct option is A Chromosomes move to the spindle equator and get aligned along equatorial plate in metaphase
During metaphase, each chromosome gets attached to two spindle fibers, one from each pole, in the region of its kinetochores. The kinetochore fibers contract and bring the chromosomes over the equator.
So, the correct answer is option A.
