Solution

The correct option is A (B)-(i) vasa efferentia, (ii) rete testis
(C)-(i) glans penis, (ii) foreskin
The seminiferous tubule is present in the testicular lobule and is highly coiled and produces sperms. The seminiferous tubule opens into the vasa efferentia (small ducts) through the rete testis (a network of interconnecting tubules where the straight seminiferous tubules empty). The enlarged part of the penis or the male genitalia is called the glans penis or head of the penis (sensitive bulbous structure at the distal end of the human penis) and is covered by a foreskin (prepuce) a double-layered fold of smooth muscle tissue, blood vessels etc, to protect the glans penis and urinary meatus.
So, the correct option is, (B)-(i) vasa efferentia, (ii) rete testis (C)-(i) glans penis, (ii) foreskin.
