Answer 1

Answer: (B)

$1$- c- iv, $2$- d- iii, $3$- b- i, $4$- a- ii

• Leydig cells or interstitial cells are present in seminiferous tubules and produce testosterone in the presence of the luteinizing hormone.
• Sertoli cell is the "nurse" cell of the testes and is located in the seminiferous tubule. They are somatic cells located within the germinal epithelium. Its main function is to nourish the developing sperm, hence, called "nurse" cells.
• Granulosa cell, also called follicular cell is closely associated with the developing female gamete or the egg in the ovary of mammals.

• Progesterone is produced by the corpus luteum in the cortex of the ovary. It helps to maintain the pregnancy.

Therefore, the correct answer is option B.
