Answer

To determine the blood donation compatibility for a person with B blood group, we need to analyze the characteristics of the B blood group and how it interacts with other blood groups.

### Step-by-Step Solution:

1. **Identify the Antigens and Antibodies**:
- The B blood group has **B antigens** on the surface of its red blood cells.
- It has **anti-A antibodies** in its plasma.

2. **Determine Who Can Receive Blood from a B Blood Group**:
- A person with B blood group can receive blood from:
- **B blood group**: Since both have B antigens, there will be no immune reaction.
- **O blood group**: O blood group has no antigens, so it does not trigger an immune response in a B blood group person.
- Therefore, a B blood group person can receive blood from **B and O blood groups**.

3. **Determine Who Can Receive Blood From a B Blood Group**:
- A person with B blood group can donate blood to:
- **B blood group**: They can receive their own blood type.
- **AB blood group**: AB blood group has both A and B antigens, so it can accept B antigens without any issue.
- Therefore, a B blood group person can donate blood to **B and AB blood groups**.

4. **Summarize the Findings**:
- A B blood group person can donate blood to: **B and AB blood groups**.
- A B blood group person can receive blood from: **B and O blood groups**.

### Final Answer:
- A B blood group person can donate blood to **B and AB blood groups** and can receive blood from **B and O blood groups**.
