Microbes that generally enter the body through nose, are likely to affect

Options

A. gut
B. lungs
C. liver
D. none of these

Explanation

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks about the effect of microbes that enter the body through the nose. It provides options: gut, lungs, liver, and none of these.

2. **Identify the Pathway**: Microbes entering through the nose typically follow a specific pathway. The nose is part of the respiratory system, which includes the nasal cavity, pharynx, larynx, trachea, bronchi, and lungs.

3. **Analyzing the Options**:
- **Gut**: The gut is part of the digestive system and is not directly connected to the nasal passage.
- **Lungs**: The lungs are directly connected to the nasal passage through the trachea and bronchi. Therefore, microbes entering through the nose are likely to affect the lungs.
- **Liver**: The liver is part of the digestive system and is also not connected to the nasal passage.
- **None of these**: This option suggests that none of the listed organs are affected, which is incorrect based on the pathway.

4. **Conclusion**: Since the nose leads directly to the lungs, the microbes that enter through the nose are most likely to affect the lungs. Therefore, the correct answer is "lungs".

5. **Final Answer**: The correct option is "lungs".
