Read the following statements and select the correct option. Statement 1 : The exaggerated response of the immune system to certain antigens present in the environment is called as allergy.
Statement 2 : The allergic tendency is genetically passed from the parent to the offspring and is characterised by the presence of large quantities of IgG antibodies in the blood.

Options

A. Both statement 1 and 2 are correct.
B. Statement 1 is correct but statement 2 is incorrect.
C. Statement 1 is incorrect but statement 2 is correct.
D. Both statement 1 and 2 are incorrect.

Answer

To determine the correctness of the statements regarding allergies, let's analyze each statement step by step.

### Step 1: Analyze Statement 1
- **Statement 1**: "The exaggerated response of the immune system to certain antigens present in the environment is called as allergy."
- **Explanation**: This statement is accurate. An allergy is indeed characterized by an exaggerated immune response to non-pathogenic antigens (allergens) such as pollen, dust mites, or certain foods. The immune system reacts excessively, leading to symptoms such as sneezing, itching, and inflammation.

### Step 2: Analyze Statement 2
- **Statement 2**: "The allergic tendency is genetically passed from the parent to the offspring and is characterized by the presence of large quantities of IgG antibodies in the blood."
- **Explanation**: This statement is partially correct. While it is true that allergic tendencies can have a genetic component, meaning they can be passed from parents to children, the second part of the statement is incorrect. Allergic reactions are primarily associated with Immunoglobulin E (IgE) antibodies, not Immunoglobulin G (IgG) antibodies. IgE is specifically involved in allergic responses, while IgG is more related to general immune responses.

### Conclusion
- **Correctness of Statements**:
- Statement 1 is correct.
- Statement 2 is incorrect.

### Final Answer
The correct option is **B**: Statement 1 is correct, but Statement 2 is incorrect.
