    Correct Answer: A

    Solution :

    [a] 1 - LH, 2 - Ovulation, 3 - Menstruation, 4 - Proliferative, 5 - Luteal LH is luteinising hormone secreted from the anterior pituitary gland. In females, an acute rise of LH (called LH surge) triggers ovulation and development of the corpus luteum. Ovulation is the process when a mature egg is released from the ovary, pushed down the fallopian tube, and is available for fertilisation. Menstruation is a woman's monthly bleeding. Menstrual blood flows from the uterus through the small opening in the cervix and passes out of the body through the vagina. Proliferative and luteal are phases of the menstrual cycle.
