Answer

**Step-by-Step Solution:**

1. **Understanding the Term**: The term 'Foramen of Panizzae' refers to an anatomical structure named after the anatomist Bartolomeo Panizza. It is essential to identify what this foramen is and where it is located.

2. **Identifying the Function**: The Foramen of Panizzae is an aperture that connects the left and right aorta in certain reptiles, specifically in crocodilians. This connection allows for the mixing of oxygenated and deoxygenated blood between the two aorta.

3. **Analyzing the Options**: The question provides four options:
- A) Middle ear of reptiles
- B) Cranium of reptiles
- C) Heart of lizards
- D) Kidney of reptiles

4. **Eliminating Incorrect Options**:
- The middle ear and cranium are not related to the Foramen of Panizzae, so options A and B can be eliminated.
- The kidneys are also not associated with this foramen, so option D can be eliminated as well.

5. **Identifying the Correct Option**: The only option left is C) Heart of lizards. However, it is important to note that the Foramen of Panizzae is specifically associated with the heart of crocodilians, which are reptiles.

6. **Conclusion**: Therefore, the correct answer to the question is that the Foramen of Panizzae is present in the heart of reptiles, specifically in crocodiles.
