• D. A-(i), B-(vi), C-(iv), D-(iii), E-(v), F-(x), G-(ix)

Answer 1

Answer: (C)

A-(i), B-(iv), C-(x), D-(iii), E-(ii), F-(vi), G-(viii)

The male sex accessory ducts are represented in the diagram that includes firstly a caput epididymis a narrow, tightly-coiled tube connecting the rear of the testicles to the vas deferens and involved in sperm storage. Vasa efferentia ducts connect and transport sperms between rete testis to the epididymis. Rete Testis network of delicate tubules located in the hilum of the testicle carries sperm from the seminiferous tubules to the efferent ducts. The vas deferens has the cauda epididymis opening into it and it ascends to the abdomen and loops over the urinary bladder. It also receives a duct from the seminal vesicle and opens into the urethra as the ejaculatory duct and is involved in the ejaculation of sperms. Seminiferous tubules are located within the testes and are the specific location of meiosis, and the subsequent creation of male gametes, namely spermatozoa. The whitish membrane within the penis that surrounds the spongy chambers (corpora cavernosa). The tunica albuginea helps to trap the blood in the corpora cavernosa, thereby sustaining an erection of the penis.

So, the correct option is ' A-(i), B-(iv), C-(x), D-(iii), E-(ii), F-(vi), G-(viii)'.
