Which of the following type of antibodies are produced during allergy ?

Options

A. Ig A
B. Ig M
C. Ig E
D. Ig G

Explanation

To determine which type of antibodies are produced during an allergy, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Allergy**:
- An allergy is a hypersensitive immune response to certain substances known as allergens (e.g., pollen, dust mites).
- The immune system reacts excessively to these allergens, leading to various symptoms.

2. **Identifying Antibody Types**:
- The human immune system produces several types of antibodies, including IgA, IgM, IgE, and IgG.
- Each type of antibody has a specific role in the immune response.

3. **Analyzing Each Antibody Type**:
- **IgA**: This antibody is primarily found in mucosal areas, such as the gut and respiratory tract, and in secretions like saliva and breast milk (colostrum). It is not specifically involved in allergic reactions.
- **IgM**: This is the first antibody produced in response to an infection but does not play a significant role in allergic responses.
- **IgE**: This antibody is specifically associated with allergic reactions. It binds to allergens and triggers the release of histamines and other chemicals from mast cells, leading to allergy symptoms.
- **IgG**: This is the most abundant antibody in the blood and provides long-term protection against pathogens. It does not play a direct role in allergic responses.

4. **Conclusion**:
- Based on the analysis, the type of antibody produced during an allergic reaction is **IgE**.

### Final Answer:
The type of antibodies produced during allergy is **IgE**.
