Hint: Menstrual cycle is monthly periods or menses. It is a series of events experienced by every girl after puberty, that are controlled by hormones for preparation of releasing an egg every month.
Complete Answer:
The length of the menstrual cycle is assumed to be 28 days. The menstrual cycle consists of four phases viz, menstrual phase, follicular phase, ovulatory phase, and luteal phase.
A) The menstrual phase is the beginning phase that starts on the first day of menstruation and lasts until the 5th day of the menstrual cycle.
B) The follicular phase is the second phase that starts on the first day of menstruation and lasts until the 13th day of the menstrual cycle.
C) The ovulation phase occurs on the 14th day of the cycle. Ovulatory phase is one of the menstrual phases. In this phase, a mature egg is released from the surface of the ovary.
D) Luteinizing Hormone (LH) from the pituitary gland is secreted that causes the ovary to release a mature egg cell. This mature egg cell travels to the fallopian tube towards the uterus. If copulation has happened then the sperm fertilizes the egg and forms a zygote. If no copulation has occurred then the released egg gets degenerated or dies within 24hours resulting in menses.
Therefore, the correct answer is option B, Ovulatory phase.
Note: Ovulation happens every 14thday of the menstrual cycle. The egg is released and lasts for 24hours. If sperm unites with an egg then it leads to pregnancy and if there is no sperm then the egg dies, this leads to bleeding in the females.
