The path of sperm transport is given below. Provide the missing steps in blank boxes.
$\boxed{\text{Seminiferous tubules}} \to \boxed{\text{Rete testis}} \to \boxed{A} \to \boxed{\text{Epididymis}} \to \boxed{B} \to \boxed{\text{Urethra}}$

(A) The correct sequence of sperm transport in the male reproductive system is:
Seminiferous tubules $\to$ Rete testis $\to$ Vasa efferentia $\to$ Epididymis $\to$ Vas deferens $\to$ Ejaculatory duct $\to$ Urethra.
Comparing this with the given flow chart:
$A = \text{Vasa efferentia}$
$B = \text{Vas deferens}$
