C)Both A and B
D)Release of hormones

Answer 1

Hint: The prostate gland is defined as a chestnut-shaped gland situated between the bladder and penis in males. The vasa deferentia constitutes sperm that are from the testes on the way to the seminal vesicles. The prostate gland is present immediately in front of the rectum. The seminal vesicles provide fluid to semen throughout ejaculation.

Complete answer:
The main function performed by the prostate gland is to emit an alkaline fluid that involves approximately 70% of the seminal volume. The secretions help in the lubrication and nourishment for the sperm. The alkaline fluid in the ejaculate helps in liquefaction of the seminal plug and aids to balance the acidic vaginal environment.

Now let us find solution from give options:
Storage of semen : Semen is a fluid that helps in the nourishment of the sperms. This is usually stored in the epididymis.
To provide motility to sperms : The main function that provides prostate gland is to provide motility to the sperms. Its emission gives food and shield to the sperms.
Both A and B : As only one of the options is correct, this option cannot be correct.
Release of hormones : The hormones such as testosterone are released by that of the testes.

Hence, the correct answer is option (B)

Note: The prostatic urethra is termed as a medium for semen and stops retrograde ejaculation by closing off the bladder neck in the climax. Ejaculation involves a synchronized narrowing of many different components, counting the smooth muscles of the seminal vesicles, vasa deferentia, ejaculatory ducts.
