DThe corpus luteum after ovulation
Answer & Solution
Correct answer: B. The mature follicle just before ovulation, with the secondary oocyte and antrum, that ruptures to release the ovum
The tertiary follicle matures into the **Graafian follicle** — a mature follicle with an antrum (fluid cavity) and secondary oocyte surrounded by zona pellucida. Its rupture **releases the ovum** (ovulation).
