The process responsible for causing menstruation is A. breakdown of the corpus luteum.

Here's a step-by-step explanation:

1. The menstrual cycle begins with the first day of the menstrual period, which is the start of the follicular phase. The main event in this phase is the development of follicles in the ovaries.

2. Around the middle of the cycle, ovulation occurs. This is when a mature egg is released from the ovary, pushed down the fallopian tube, and is available to be fertilized.

3. The second half of the cycle is called the luteal phase. After the egg has been released, the ruptured follicle closes after releasing the egg and forms a structure called the corpus luteum, which produces progesterone.

4. If the egg is not fertilized, the corpus luteum breaks down and stops producing progesterone. This drop in progesterone levels causes the lining of the uterus to shed, which is known as menstruation.

5. If the egg is fertilized, it attaches to the endometrium and the corpus luteum continues to produce progesterone to maintain the pregnancy. If the egg does not implant in the endometrium, the corpus luteum breaks down and menstruation occurs.

So, the breakdown of the corpus luteum is the process that triggers menstruation.
