Which of the following is the correct option for decreases order of concentrations of different types of antibodies which are produced in our body ?

Options

A. IgG, IgA, IgM, IgD, IgE
B. IgM, IgG, IgA, IgD, IgE
C. IgE, IgD, IgM, IgA, IgG
D. IgE, IgD, IgA, IgG, IgM

Answer

To determine the correct order of concentrations of different types of antibodies produced in our body, we need to analyze the percentages of each antibody type present in the blood plasma.

### Step-by-Step Solution:

1. **Identify the Types of Antibodies**: The main types of antibodies (immunoglobulins) are IgG, IgA, IgM, IgD, and IgE.

2. **Determine the Concentration of Each Antibody**:
- **IgG**: 75% of antibodies in blood plasma
- **IgA**: 15% of antibodies in blood plasma
- **IgM**: 5% of antibodies in blood plasma
- **IgD**: 0.25% of antibodies in blood plasma
- **IgE**: 0.05% of antibodies in blood plasma

3. **Arrange the Antibodies in Decreasing Order of Concentration**:
- Start with the highest concentration: **IgG (75%)**
- Next is **IgA (15%)**
- Followed by **IgM (5%)**
- Then **IgD (0.25%)**
- Finally, **IgE (0.05%)**

4. **Final Order**: The correct order of decreasing concentrations of antibodies is:
- **IgG > IgA > IgM > IgD > IgE**

5. **Select the Correct Option**: Based on the order determined, the first option provided in the question is correct.
