Which of the following is responsible for asthmatic attacks ?

Options

A. Inhalation of pollen
B. Cold wealth
C. Eating vegetables grown in polluted water
D. All the above

Answer

**Step-by-Step Solution:**

1. **Identify the Question**: The question asks which factor is responsible for asthmatic attacks.

2. **Consider the Options**: The options provided include various environmental factors. We need to analyze each option to determine which one is linked to asthma.

3. **Understanding Pollen Grains**: Pollen grains are typically larger in size. However, when they come into contact with water (like during rainfall), they can break down into smaller particles.

4. **Mechanism of Asthmatic Attacks**: These smaller particles can be inhaled and penetrate deeper into the lungs. The body may react to these particles, triggering an asthmatic response.

5. **Evaluate Other Options**: The other options, such as cold weather and consuming vegetables grown in polluted water, do not have a direct link to causing asthmatic attacks compared to inhaling pollen.

6. **Conclusion**: Based on the analysis, the inhalation of pollen (especially when it has been broken down into smaller particles) is responsible for triggering asthmatic attacks.

7. **Final Answer**: The correct answer is **inhalation of pollen**.
