C. Seminal vesicle - single
D. Bulbourethral gland - paired

Options

A. A, B
B. A, B, D
C. C, D
D. A, B, C, D

Answer

To determine which matches are correct regarding the anatomical structures mentioned in the question, we will analyze each option step by step.

### Step 1: Analyze Option A - Urethra
- The urethra is a duct that carries urine from the urinary bladder to the exterior of the body.
- It is a single structure in both males and females.
- **Conclusion**: Option A is correct.

### Step 2: Analyze Option B - Prostate Gland
- The prostate gland is an accessory reproductive gland found in males.
- It is also a single structure, meaning there is only one prostate gland in the male reproductive system.
- **Conclusion**: Option B is correct.

### Step 3: Analyze Option C - Seminal Vesicle
- The seminal vesicles are accessory reproductive glands in males.
- There are two seminal vesicles, making them a paired structure.
- The option states that it is single, which is incorrect.
- **Conclusion**: Option C is incorrect.

### Step 4: Analyze Option D - Bulbourethral Gland
- The bulbourethral glands (also known as Cowper's glands) are accessory reproductive glands in males.
- They are paired structures, meaning there are two bulbourethral glands.
- **Conclusion**: Option D is correct.

### Final Conclusion
- The correct matches are:
- A (Urethra - single) - Correct
- B (Prostate gland - single) - Correct
- C (Seminal vesicle - single) - Incorrect
- D (Bulbourethral gland - paired) - Correct

Thus, the correct options are A, B, and D.
