Options

A. pronephric
B. metanephric
C. mesonephric
D. none of the above

Answer

To answer the question "In rabbit and humans, the kidney is pronephric, metanephric, mesonephric or none," we can follow these steps:

### Step 1: Understand the Types of Kidneys
- **Pronephric**: This is a temporary kidney that is present during the embryonic stages of some vertebrates, such as fish and amphibian larvae.
- **Mesonephric**: This type of kidney functions in some aquatic vertebrates and serves as a temporary kidney in reptiles, birds, and mammals.
- **Metanephric**: This is the most advanced type of kidney found in adult amniotes (reptiles, birds, and mammals). It is a paired organ with functional units called nephrons.

### Step 2: Identify the Type of Kidney in Rabbits and Humans
- Both rabbits and humans are mammals, and they possess a more advanced kidney structure.
- The kidneys in both species are classified as metanephric kidneys.

### Step 3: Conclusion
- Therefore, the correct answer to the question is that in rabbits and humans, the kidney is **metanephric**.

### Final Answer
In rabbit and humans, the kidney is **metanephric**.
