Answer:

Menstrual cycle

The Menstrual cycle is a term used to depict the events that happen inside a lady's body as it gets ready for the possibility of pregnancy every month. A monthly cycle is considered to start on the 1st day of a period. The typical cycle is 28 days in length; be that as it may, a cycle can go long from 21 days to around 35 days.

Explanation:

• The events in the period are set off by the ascent and fall of synthetic compounds in the body called hormones.
• The pituitary organ in the brain and the ovaries in the female reproductive tract forms and delivers certain hormones at specific times during the monthly menstrual cycle that make the organs of the conceptive reproductive tract act in specific ways.

• Menstrual cycle occurs in Primates only.

1. There is absence of Heat period and Copulation or Fertilization occurs only at the time of cycle.
2. The broken endometrium (The Uterine lining starts to shed if no fertilization occurs in an individual after the Ovulation period is over the Unfertilized Ovum turns to Luteal phase and thus begins the Follicular phase) is passed out during Menstruation.
3. Examples- Monkeys, Apes and Human beings.

• Whereas,
• Option (B),(C),(D)- Monkeys, Apes, Humans all undergo Menstrual cycle, elaborated above.
