Human Reproduction

To solve this problem, we need to identify the correct term for the fluid combination of seminal plasma and sperm.

1. Understanding Seminal Plasma:
Seminal plasma is the fluid secreted by accessory reproductive glands such as seminal vesicles, prostate gland, and Cowper's (bulbourethral) glands. It provides nutrients, protection, and a medium for sperm motility.

2. Combination of Seminal Plasma and Sperm:
When seminal plasma mixes with spermatozoa produced in testes, it collectively forms semen. Semen is the fluid ejaculated during sexual intercourse.

3. Evaluating Options:
(1) Plasma – Incorrect (a general term unrelated specifically to reproductive fluids).
(2) Semen – Correct (semen consists of seminal plasma and sperm).
(3) Placenta – Incorrect (involved in fetal development and not related to seminal fluids).
(4) None of the above – Incorrect (option (2) is correct).

Final Answer:
The correct option is (B) Semen.
