In the ABO system of blood,group,if both antigens are present but no antibody,the blood group of the individual would be :

Options

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

Explanation

To determine the blood group of an individual in the ABO system when both antigens are present but no antibodies are found, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the ABO Blood Group System**: The ABO blood group system consists of four main blood types: A, B, AB, and O. Each blood type is defined by the presence or absence of specific antigens (A and B) on the surface of red blood cells (RBCs).

2. **Identify Antigens and Antibodies**:
- **Blood Group A**: Has A antigens on RBCs and produces anti-B antibodies in the plasma.
- **Blood Group B**: Has B antigens on RBCs and produces anti-A antibodies in the plasma.
- **Blood Group AB**: Has both A and B antigens on RBCs and does not produce any antibodies against A or B antigens.
- **Blood Group O**: Has no antigens on RBCs and produces both anti-A and anti-B antibodies.

3. **Analyze the Given Condition**: The question states that both antigens (A and B) are present, but there are no antibodies. This means that the individual cannot have blood groups A, B, or O, as they all produce antibodies against the other antigens.

4. **Conclusion**: The only blood group that has both A and B antigens present without producing any antibodies is blood group AB. Therefore, if both antigens are present and no antibodies are found, the blood group of the individual must be AB.

5. **Final Answer**: The blood group of the individual would be AB.
