Which of the following organ is a paired structure ?

Options

A. Urethra
B. Prostate
C. Scrotum
D. Ejaculatory duct

Answer

To determine which of the following organs is a paired structure, we will analyze each option provided in the question.

### Step-by-Step Solution:

1. **Identify the Options**: The options provided are urethra, prostate, scrotum, and ejaculatory duct.

2. **Analyze the Urethra**:
- The urethra is a tube-like structure that carries urine from the urinary bladder to the outside of the body.
- It is a single structure in males and females.
- **Conclusion**: Urethra is not a paired structure.

3. **Analyze the Prostate**:
- The prostate is a gland that produces fluid that nourishes and transports sperm.
- There is only one prostate gland present in males.
- **Conclusion**: Prostate is not a paired structure.

4. **Analyze the Scrotum**:
- The scrotum is a pouch that contains the testicles (testes).
- Although it holds two testicles, the scrotum itself is a single structure.
- **Conclusion**: Scrotum is not a paired structure.

5. **Analyze the Ejaculatory Duct**:
- The ejaculatory duct is responsible for transporting sperm from the testis to the urethra.
- Each testis has its own ejaculatory duct, and since there are two testicles, there are two ejaculatory ducts.
- **Conclusion**: Ejaculatory duct is a paired structure.

### Final Answer:
The organ that is a paired structure is the **ejaculatory duct**.
