• A. A - (iv), B - (i), C - (ii), D - (iii), E - (v)
• B. A - (ii), B - (i), C - (iv), D - (iii), E - (v)
• C. A - (ii), B - (i), C - (v), D - (iv), E - (iii)
• D. A - (iv), B - (i), C - (ii), D - (v), E - (iii)

Answer 1

The correct option is D A - (iv), B - (i), C - (ii), D - (v), E - (iii)

The hypothalamus is a small region of the brain. It's located at the base of the brain, near the pituitary gland. It secretes hypothalamic hormone such as the GnRH or Gonadotropin stimulating hormone which further has effects on the pituitary gland. The acrosome is the anterior covering on the head of the sperm that consists of enzymes called lysins that can lyse the ovum membrane to penetrate and fertilize it. A Graafian follicle is a developed tertiary follicle and is responsible for the ovulation that occurs as a result of the surge in FSH and LH levels responsible for estrogen production. Leydig cells in the seminiferous tubules are responsible for the secretion of androgens such as testosterone. Parturition is the process of the delivery of the fetus and during this process, Relaxin is a hormone produced by the ovary and the placenta with important effects in the female reproductive system and during pregnancy.

So, the correct option is 'A - (iv), B - (i), C - (ii), D - (v), E - (iii)'.
