Final Answer :
A
Explanation :
During ovulation, the mature follicle ruptures and releases the secondary oocyte along with the corona radiata and the zona pellucida. However, the granulosa cells that surrounded the oocyte are left behind and form the corpus luteum, which produces hormones to prepare the uterus for possible pregnancy.
