Universal blood recipient is

Options

A. Blood group O
B. Blood group AB
C. Blood group A
D. Blood group B

Answer

To determine the universal blood recipient, we need to analyze the ABO blood group system and understand the characteristics of each blood type.

### Step-by-Step Solution:

1. **Understand Blood Groups**: The ABO blood group system consists of four main blood types: A, B, AB, and O. Each blood type has specific antigens and antibodies associated with it.

2. **Identify Antigens and Antibodies**:
- **Blood Group A**: Has A antigens and produces anti-B antibodies.
- **Blood Group B**: Has B antigens and produces anti-A antibodies.
- **Blood Group AB**: Has both A and B antigens and does not produce any antibodies against A or B. This means it can accept blood from any other group without causing an immune reaction.
- **Blood Group O**: Has no antigens and produces both anti-A and anti-B antibodies. This means it can only receive blood from other O type donors.

3. **Determine the Universal Recipient**: The universal recipient is the blood type that can receive blood from all other blood types without any adverse reactions. Since blood group AB has no antibodies against A or B antigens, individuals with this blood type can receive blood from A, B, AB, or O blood types.

4. **Conclusion**: Therefore, the universal blood recipient is **blood group AB**.

### Final Answer:
The universal blood recipient is **blood group AB**.
