Final answer:
The capsule covering the testes is the tunica albuginea, and the anterior sac of peritoneum is called the tunica vaginalis, making the answer A) Tunica albuginea, vaginalis.
Step-by-step explanation:
The testes are covered by a capsule called tunica albuginea, and the anterior sac of peritoneum is referred to as the tunica vaginalis. Thus, the correct answer to the given question is A) Tunica albuginea, vaginalis. The tunica albuginea is a tough, white, dense connective tissue layer that not only covers the outside of the testis but also extends inside to form septa, dividing the testes into structures known as lobules.
Seminiferous tubules, where sperm develop, are located within these lobules. The tunica vaginalis is a serous membrane that envelops the tunica albuginea and consists of a parietal layer lining the scrotal cavity and a visceral layer covering the testes.
