Identify the correct passage of spermatozoa in the male human reproductive system.
(a) Vas deferens
(b) Epididymis
(c) Urethra
(d) Vasa efferentia
(e) Ejaculatory duct
(f) Seminiferous tubules.

The correct option is B f$\to$ d $\to$ b $\to$ a $\to$ e $\to$ c
In the male reproductive system, spermatozoa released from the seminiferous tubules move to the rete testis, then via the vasa efferentia, they move to the epididymis where they are stored. On the event of copulation, they travel through the vas deferens into the ejaculatory duct and are then released via the urethra.

So, the correct answer is 'f→→ d →→ b →→ a →→ e →→ c'.
