Answer: (C)

Verified step by step guidance

1. Understand the components of semen: Semen is composed of sperm and various fluids that provide nutrients and aid in the transport of sperm.
2. Identify the role of each gland in the male reproductive system: The testes produce sperm, the seminal vesicles contribute a significant portion of the fluid that makes up semen, the prostate gland adds additional fluid, and the bulbourethral glands secrete a small amount of fluid for lubrication.
3. Focus on the seminal vesicles: These glands are responsible for producing approximately 60-70% of the seminal fluid. This fluid contains fructose and other substances that nourish and help transport sperm.
4. Compare the contributions of each gland: While the prostate gland and bulbourethral glands contribute to the composition of semen, their contributions are smaller compared to the seminal vesicles.
5. Conclude that the seminal vesicles are the primary source of seminal fluid production in the male reproductive system, making them the correct answer to the question.
