Answer 1

The correct option is B $\begin{array}{cccc}\text{A}& \text{B}& \text{C}& \text{D}\\ 3& 2& 1& 4\end{array}$

Leydig cells, sertoli cells and rete testis are parts of male reproductive system.

• Leydig cells help in synthesis and secretion of the male hormones (androgens) like testosterone.
• Sertoli cells or nurse cells provide nutrition to the sperms.
• Rete testis carries sperms from seminiferous tubules to vasa efferentia.

Corpus luteum is the structure formed from the ruptured graafian follicles after ovulation in the female reproductive system. It secretes large amount of progesterone essential for the maintenance of endometrium.
