Solution
The correct option is C30 Meiosis is a characteristic division of the reproductive cells. It is also called reduction division because, the parent cell produces four daughter cells each having half the number of chromosomes present in the parent cell. In metaphase I, the spindle formation is complete. The bivalents move and arrange themselves on equatorial plane. Therefore if the number of chromosomes at the equatorial plate is 2n=60, then the number of chromosomes will be 30.
