AIIMS 2017 Botany Male Reproductive System MCQ Question

Option C is correct because the seminal vesicles produce a fluid that is rich in fructose, prostaglandins, and proteins, contributing approximately 60-70% of the total volume of semen, while the prostate gland, which is option B, secretes a fluid containing calcium, fibrinolysin, and acid phosphatase, contributing about 30% of the semen volume. Option A, Cowper's glands, primarily secrete a pre-ejaculatory fluid that helps lubricate the urethra and neutralize acidity but does not significantly contribute to semen volume. Option D, the epididymis, is responsible for sperm maturation and storage, not fluid secretion.
