D. Humming bird

Answer

### Step-by-Step Solution:

1. **Understanding the Question**: The question asks about the smallest egg found in a specific animal. We need to analyze the options provided to determine which animal lays the smallest egg.

2. **Analyzing the Options**:
- **Homo sapiens**: This refers to humans. Humans are viviparous, meaning they give birth to live young and do not lay eggs. Therefore, this option can be eliminated.
- **Columba (Pigeon)**: Pigeons are oviparous, meaning they lay eggs. However, we need to compare the size of their eggs with other options.
- **Struthio (Ostrich)**: Ostriches are known for laying the largest eggs among birds. This option can also be eliminated as we are looking for the smallest egg.
- **Hummingbird**: Hummingbirds are known for laying very small eggs compared to other birds.

3. **Comparing the Remaining Options**: After eliminating Homo sapiens and Struthio, we are left with Columba (Pigeon) and Hummingbird.

4. **Identifying the Correct Answer**: Among the remaining options, the hummingbird is known to have the smallest egg size when compared to the pigeon. Therefore, the correct answer is the hummingbird.

5. **Final Conclusion**: The smallest egg is found in the hummingbird.
