Answer:
The correct answer is a. Seminal vesicle
Explanation:
Seminal vesicles are the pair of glands that are found in the male pelvic region below the urinary bladder. Seminal vesicles produce about 60% of fluid present in the total semen ejaculate therefore without seminal secretion semen would be very low in volume.
The seminal fluid contains nutrients like fructose that provide energy to the sperms, phosphorus and potassium that helps in the motility of sperms. Seminal fluid is alkaline in nature which protects sperms from the acidic environment in the vagina. Therefore the correct answer is a. Seminal vesicle.
