Options

A. Ureter
B. Nephron
C. Seminiferous tubules
D. Uriniferous tubles

Answer

**Step-by-Step Solution:**

1. **Identify the Question**: The question asks for the morphological and physiological unit of the vertebrate kidney.

2. **Understand the Options**: The options provided are:
- Option 1: Ureter
- Option 2: Nephron
- Option 3: Seminiferous tubules
- Option 4: Uriniferous tubules

3. **Analyze Each Option**:
- **Ureter**: This is a tube that carries urine from the kidney to the bladder, but it is not a functional unit of the kidney itself.
- **Nephron**: This is the basic structural and functional unit of the kidney responsible for urine formation and waste removal.
- **Seminiferous tubules**: These are found in the testes and are involved in sperm production, not related to the kidney.
- **Uriniferous tubules**: This term can sometimes refer to the nephron but is not as commonly used as nephron itself.

4. **Select the Correct Answer**: Based on the analysis, the nephron is the correct answer as it is the morphological and physiological unit of the vertebrate kidney.

5. **Conclusion**: Therefore, the answer to the question is **Option 2: Nephron**.
