Answer

Brief Explanations:

To determine the process causing menstruation, we analyze each option:

  • Option A: The corpus luteum secretes progesterone to maintain the endometrium. If fertilization doesn't occur, the corpus luteum breaks down, leading to a drop in progesterone. This drop causes the endometrial lining to shed, resulting in menstruation.
  • Option B: Fertilization would prevent menstruation as it leads to pregnancy.
  • Option C: Implantation occurs during pregnancy, which stops menstruation.
  • Option D: Rupture of a follicle (ovulation) releases the egg, but it doesn't directly cause menstruation.
  • Option E: Repair of the endometrial lining happens after menstruation, not during or as the cause of it.

Answer:

A. breakdown of the corpus luteum
