A person with blood group B requires blood. The blood group which can be given is

Options

A. O and B
B. A and AB
C. A and O
D. A, B, AB and O

Answer

To determine which blood groups can be given to a person with blood group B, we need to consider the compatibility of blood types based on the presence of antigens and antibodies.

### Step-by-Step Solution:

1. **Understand Blood Group Antigens and Antibodies**:
- Blood groups are determined by the presence of specific antigens on the surface of red blood cells (RBCs).
- Blood group B has B antigens on the RBCs and produces antibodies against A antigens.

2. **Identify Compatible Blood Groups**:
- A person with blood group B can receive blood from:
- Other individuals with blood group B (since they have the same B antigens).
- Individuals with blood group O (since O has no antigens and does not trigger an immune response).

3. **List of Compatible Donors**:
- Therefore, the compatible blood groups for a person with blood group B are:
- Blood group B
- Blood group O

4. **Conclusion**:
- The blood group that can be given to a person with blood group B is either B or O.

### Final Answer:
The blood groups that can be given to a person with blood group B are B and O.
