Solution
The correct option is D (ii) > (i) > (iii)
Seminal vesicles produce an alkaline secretion which forms 60% of the volume of semen. The secretion of the seminal vesicles contains fructose, prostaglandins, citrate, inositol, and clotting proteins. The prostate gland produces a milky and slightly alkaline secretion which forms 25% of the volume of semen. It possesses calcium, phosphate, bicarbonate, enzymes prefibrolysin, clotting enzymes, and prostaglandins. Bulbourethral glands or Cowper's glands also secrete an alkaline fluid which neutralizes acids from urine in the urethra. Their secretion contributes the least to semen but is very important.
