Column $I$	Column $II$
$(a)$ Seminiferous tubules	$(1)$ Site for storage and maturation of sperm
$(b)$ Urethra	$(2)$ Structure which releases sperm cells

$(d)$ Epididymis	$(4)$ Coiled duct where sperm development begins

(A) $(a - 4), (b - 2), (c - 3), (d - 1)$
Explanation:
- $(a)$ Seminiferous tubules are highly coiled structures within the testes where spermatogenesis (sperm development) begins.
- $(b)$ The urethra acts as the common passage for both urine and semen, facilitating the release of sperm cells.
- $(c)$ Seminal vesicles are paired accessory glands that secrete a fluid rich in fructose and other nutrients for sperm.
- $(d)$ The epididymis is the site where sperm are stored and undergo physiological maturation before ejaculation.
