The correct answer is a) Systemic acquired resistance
Explanation:
In biology, systemic acquired resistance occurs as one organism develops resistance to a specific pathogen such as a virus or bacteria, this means, the organism's system recognizes previous pathogens it has been exposed to and in this way responds appropriately. The systemic acquired resistance occurs mainly in plants and due to this, it is believed this response is similar to one of the immune systems in animals. Therefore, the mechanism that is the closest process plants have to an immune system is Systemic Acquired Resistance or SAR.

Menstrual cycle is a complex cycle that consists of several processes. Order of occurrence of steps in menstrual cycle are as follows:
1. High progesterone levels maintain the endometrium lining of the uterus.
2. Endometrium lining breaks down and low levels of estrogen stimulate the pituitary to release FSH and LH.
3. FSH and LH stimulates the follicles to develop and the oocyte to produce estrogen.
4. Rising estrogen levels suppress FSH production and development of other follicles.
5. A spike in LH causes follicle to rupture.
6. A breakdown of corpus luteum causes progesterone level to drop.
