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).

Protective proteinous chemical compounds produed by the immune cells in response to antigens are called antibodies, also called immunoglobulins. There are five classes of antibodies: IgA, IgD, IgE, IgG and IgM. Following diagram is that of a specific class of antibodies. Observe the diagram and answer the questions listed below the diagram: (i) To which class of antibodies, this antibody belongs to ? (ii) Identify the parts of the diagram labelled as A and B. (iii) Give the name of the part of antibody which binds the antigen. (iv) Which type of immune system is formed by the antibodies?

A yound boy when brough a pet dog home started to complain of watery eyes and running nose. The symptoms disappeared when the boy was kept away from the pet. (a) Name the type of antibody and the chemicals responsible for such a response in the boy. (b) Mention the name of any one drug that could be given to the boy for immediate relief from such a response.
