Yellowish glandular structure which produces progesterone is_____________?
Correct answer: C. Corpus luteum
- A. Graffian follicle
- B. Ovary
- C. Corpus luteum
- D. Placenta
Explanation
After ovulation, the ruptured Graafian follicle changes into the corpus luteum, a yellow endocrine structure that secretes progesterone. Progesterone maintains the uterine lining for possible implantation. The Graafian follicle is the precursor, so choosing it confuses the structure before ovulation with the progesterone-secreting structure after ovulation.

About Menstrual Cycle
The menstrual cycle covers the coordinated changes in the ovaries and uterus, including menstruation, follicular growth, ovulation and corpus luteum formation. It links follicle-stimulating hormone, luteinizing hormone, oestrogen and progesterone with endometrial changes, and distinguishes the ovarian cycle from the uterine cycle and the hormonal events of pregnancy.
