A) (iii), (iv) and (vi) only
B) (ii), (v) and (vi) only
C) (i), (ii) and (iv) only
D) (i), (iii) and (v) only
Correct Answer: A
Solution :
In the given figure, E is epididymis, F is vas deferens, G is seminal vesicle, H is testis, / is urethra and J is scrotum. Seminal vesicle (G) produces 60% of the volume of semen and contains fructose, prostaglandins and some clotting proteins. Testis (H) is a primary sex organ of male that produces haploid gametes, i.e., sperms. Scrotum (J) is an extra abdominal pouch that keeps testicular temperature \[2{}^\circ -2.5{}^\circ C\] lower than the normal body temperature. This temperature is required for the formation of sperms in the testes.
