Correct option:(B)Fibrinogen
Solution:
- Semen is made up of sperm cells and seminal fluid.
- Seminal fluid majorly contains clear and viscous secretions.
- These secretions provide vitamin C, fructose, and fibrinogen to the ejaculated sperm.
- Fibrinogen helps in seminal clotting on ejaculation.
- Clots the semen and thus helps to keep the ejaculated sperm in the female reproductive tract.
