The correct Answer is:
To analyze the condition described in the question, we need to evaluate each statement in relation to the symptoms of sneezing and wheezing, which are indicative of an allergic reaction. ### Step-by-Step Solution: 1. **Understanding the Condition**: The symptoms of sneezing and wheezing suggest that the person is experiencing an allergic reaction. Allergies occur when the immune system overreacts to certain substances (allergens) in the environment. **Hint**: Look for symptoms that are commonly associated with allergic reactions. 2. **Evaluating Statement (i)**: "This is an exaggerated response of the immune system." - This statement is correct. Allergic reactions are indeed exaggerated responses of the immune system to harmless substances. **Hint**: Consider how the immune system responds to allergens compared to normal responses. 3. **Evaluating Statement (ii)**: "Symptoms are watery eyes and running nose." - This statement is also correct. Watery eyes and a running nose are common symptoms of allergies. **Hint**: Recall the typical symptoms of allergic reactions. 4. **Evaluating Statement (iii)**: "Due to the release of chemicals like adrenaline, steroids, and histamine." - This statement is partially incorrect. While histamine is released during allergic reactions, adrenaline and steroids typically act to reduce the symptoms of allergies rather than cause them. **Hint**: Identify which chemicals are primarily involved in allergic reactions. 5. **Evaluating Statement (iv)**: "Antibodies produced to these are IgE type." - This statement is correct. In allergic reactions, the immune system produces IgE antibodies in response to allergens. **Hint**: Remember the role of different antibody types in immune responses. ### Conclusion: The correct statements that correlate with the condition of sneezing and wheezing are: - (i) This is an exaggerated response of the immune system. - (ii) Symptoms are watery eyes and running nose. - (iv) Antibodies produced to these are IgE type. Therefore, the correct statements are (i), (ii), and (iv). ### Final Answer: The correct statements are (i), (ii), and (iv).
