The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding the Assertion:** - The assertion states that "Asthma is a difficulty in breathing causing wheezing." - This is true as asthma is characterized by difficulty in breathing due to narrowed airways, which can lead to wheezing sounds during respiration. 2. **Understanding the Reason:** - The reason states that "Asthma occurs due to inflammation of bronchi and bronchioles." - This is also true. In asthma, the airways (including bronchi and bronchioles) become inflamed, which leads to swelling and increased mucus production, contributing to the difficulty in breathing. 3. **Connecting Assertion and Reason:** - The assertion and reason are closely linked. The inflammation of the bronchi and bronchioles (the reason) directly leads to the symptoms of asthma, including difficulty in breathing and wheezing (the assertion). 4. **Conclusion:** - Both the assertion and the reason are correct, and the reason provides a valid explanation for the assertion. Therefore, we can conclude that the assertion is true and the reason is also true, with the reason being the correct explanation for the assertion. **Final Answer:** - Both the assertion and the reason are correct, and the reason is the correct explanation for the assertion. ---
