Hint: The substance called semen is made up of secretions from the epididymis, prostate, seminal vesicles, and bulbourethral gland, along with sperm.

Complete Answer:
Semen, also referred to as seminal fluid, is a fluid released from the male reproductive tract containing sperm cells responsible for fertilising the eggs of the female. Semen also includes liquids that mix to create seminal plasma, helping to preserve the viability of the sperm cells.

- Sperm cells are formed by the testes in the sexually mature human male and they make up just around 2 to 5 % of the overall semen content. Thus, option A is not the correct option.

- Liquids from the prostate gland and seminal vesicles are applied during the ejaculation process , helping to dilute the sperm concentration and provide an environment that is suitable for them. Thus, option B is not the correct option.

- Only 1 percent of semen is made up of sperm. The remainder is a fluid secretion from the accessory glands, which includes fructose to neutralise urethral (urine acidity) and vaginal acidity to nurture sperm and alkaline medium, and includes a liquid medium for the motility of sperm. Vitamin C and trace elements such as calcium, magnesium, zinc, copper, and sulphur are also found.

- Approximately 30% of the seminal fluid is contributed by the prostate gland; its secretion components are primarily acid phosphatase, sodium , citric acid, potassium, fibrinolysin, calcium , zinc, and protein-splitting enzymes. Thus, option D is not the correct option.

Thus, the correct answer is option (C) To provide a medium for movement of sperms.

Note: The bulbourethral and urethral glands secrete a small volume of fluid; this is a dense, smooth, lubricating substance frequently referred as mucus. In semen, sulphate chemicals actually prevent sperm cells from expanding, and the key food for sperm cells is fructose.
