Final answer:
In the male reproductive system, sperm becomes semen after being mixed with fluids from the seminal vesicles and the prostate gland. The false statement regarding the prostate gland being in the testes should be corrected to reflect that it is located beneath the bladder.
Step-by-step explanation:
In the male reproductive system, sperm becomes semen when it is mixed with seminal fluids. These fluids are produced primarily by the seminal vesicles and the prostate gland. The correct answer to the question is 'b) Prostate Gland'.
Sperm are produced in the seminiferous tubules within the testes. After sperm is produced, it is stored in the epididymis. When ejaculation occurs, sperm travels through the vas deferens, mixes with the seminal fluids from the prostate gland and the seminal vesicles, and the resultant fluid is called semen.
