Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks about the health effects caused by cotton dust exposure. We need to identify the correct lung disease associated with inhaling cotton dust.

2. **Reviewing the Options**: The options provided are:
- Option 1: Silicosis
- Option 2: Siderosis
- Option 3: Pneumoconiosis
- Option 4: Byznosis

3. **Analyzing Each Option**:
- **Option 1: Silicosis**: This disease is caused by inhaling silica dust, which is found in rocks. Since cotton dust does not contain silica, this option is incorrect.
- **Option 2: Siderosis**: This condition results from inhaling iron dust, typically associated with iron and mining industries. Cotton dust is not related to iron, making this option incorrect as well.
- **Option 3: Pneumoconiosis**: This is a general term for lung diseases caused by inhaling various types of dust, including coal dust. However, it does not specifically refer to cotton dust, so this option is also not correct.
- **Option 4: Byznosis**: This disease is specifically caused by inhaling dust from hemp, flax, and cotton. It is also referred to as brown lung disease and primarily affects workers in the cotton industry. This makes it the correct option.

4. **Conclusion**: Based on the analysis, the correct answer to the question "Cotton dust causes" is **Option 4: Byznosis**.
