C.The level of FSH rises significantly during this phase.
D.In this phase, the follicle ruptures, releasing a mature ovum.

Answer

• In this phase, the follicle ruptures, releasing a mature ovum.
  Explanation:
  FSH initiates maturation of the oocyte and begins to decline until ovulation. Increase/surge in LH triggers ovulation as the follicle enlarges rapidly after 24 to 36 hours, which causes rapture of the follicle, releasing a mature ovum. After ovulation, a surge of progesterone begins to help prepare the uterine lining for implantation.
