You're welcome.

Yes, you are correct. The correct answer is D. Prostate gland.

To arrive at this answer, we need to have an understanding of human anatomy and specifically the male reproductive system.

The prostate gland is a part of the male reproductive system and is located just below the urinary bladder. It is about the size of a walnut and surrounds the urethra, which is the tube that carries urine from the urinary bladder to the outside of the body. The prostate gland produces fluid that helps nourish and transport sperm during ejaculation.

On the other hand, the other options mentioned are not correct for this question:

A. Testis: The testis is a male reproductive organ responsible for producing sperm and testosterone. It is not located near the urethra or the urinary bladder.

B. Gonad: The term "gonad" refers to the general reproductive organs, which include the testes in males and ovaries in females. It does not specifically refer to the prostate gland.

C. Thyroid gland: The thyroid gland is a part of the endocrine system and is located in the neck region. It produces hormones that regulate metabolism. It is not located near the urethra or the urinary bladder.

Therefore, the correct answer is D. Prostate gland.
