Anti-A and Anti-B antibodies are not found in which of the following blood group ?

Options

A. AB
B. A
C. O
D. B

Answer

To determine in which blood group anti-A and anti-B antibodies are absent, we can follow these steps:

### Step-by-Step Solution:

1. **Understand Blood Groups**: Blood groups are classified based on the presence of specific antigens on the surface of red blood cells (RBCs) and the presence of corresponding antibodies in the plasma.

2. **Identify Antigens and Antibodies**:
- **Blood Group A**: Has A antigens on RBCs and anti-B antibodies in plasma.
- **Blood Group B**: Has B antigens on RBCs and anti-A antibodies in plasma.
- **Blood Group AB**: Has both A and B antigens on RBCs and no antibodies (neither anti-A nor anti-B) in plasma.
- **Blood Group O**: Has no antigens on RBCs and has both anti-A and anti-B antibodies in plasma.

3. **Analyze the Question**: The question asks for the blood group where both anti-A and anti-B antibodies are absent.

4. **Conclusion**: From the analysis, we see that blood group AB is the only group that does not have any antibodies (anti-A and anti-B) in the plasma.

5. **Final Answer**: Therefore, the correct answer is **Blood Group AB**.
