A person having blood group 'O' can receive blood of :

Options

A. Group O, B and AB
B. Group B, O and AB
C. Group B and AB
D. Group 'O' only

Answer

To determine which blood groups a person with blood group 'O' can receive, we need to understand the characteristics of blood groups and the presence of antigens and antibodies.

### Step-by-step Solution:

1. **Understanding Blood Group O**:
- Blood group O has no antigens (A or B) on the surface of the red blood cells.
- It contains both anti-A and anti-B antibodies in the plasma.

2. **Compatibility of Blood Groups**:
- **Blood Group A**: Has A antigens and anti-B antibodies. Therefore, it cannot be given to a person with blood group O because the anti-B antibodies in group O will attack the A antigens.
- **Blood Group B**: Has B antigens and anti-A antibodies. Similarly, it cannot be given to a person with blood group O because the anti-A antibodies in group O will attack the B antigens.
- **Blood Group AB**: Has both A and B antigens but no antibodies. A person with blood group O cannot receive blood from AB because the anti-A and anti-B antibodies in group O will attack both A and B antigens.

3. **Conclusion**:
- A person with blood group O can only receive blood from another person with blood group O. This is because group O does not have any antigens that could trigger an immune response against the transfused blood.

### Final Answer:
A person having blood group 'O' can receive blood of group **O only**.
