The blood from a person with an AB blood type

Options

A. Would agglutinate with both anti-A and anti-B antibodies
B. Would not agglutinate with either anti-A and anti-B antibodies
C. Would agglutinate with anti-A antibodies only
D. Would agglutinate with anti-B antibodies only

Answer

To answer the question regarding the blood from a person with an AB blood type, we need to understand the characteristics of blood types and the presence of antibodies.

### Step-by-Step Solution:

1. **Understanding Blood Types**: Blood types are determined by the presence or absence of specific antigens on the surface of red blood cells (RBCs). The main blood group antigens are A and B.

2. **AB Blood Type Characteristics**: A person with AB blood type has both A and B antigens present on the surface of their RBCs. This means their blood cells can accept both A and B blood types without any adverse reactions.

3. **Antibody Production**: In the plasma of a person with AB blood type, there are no antibodies against A or B antigens. This is crucial because antibodies are produced against antigens that are not present on the individual's own RBCs.

4. **Evaluating the Options**:
- **Option 1**: "It is written with both anti-A and anti-B antibodies." - This is incorrect because AB blood type does not produce these antibodies.
- **Option 2**: "It is written with both anti-A and anti-B antibodies." - This is a repetition of Option 1 and is also incorrect.
- **Option 3**: "It is written with anti-A antibodies only." - This is incorrect as AB blood type does not have any anti-A antibodies.
- **Option 4**: "It is written with anti-B antibodies only." - This is also incorrect as AB blood type does not have any anti-B antibodies.

5. **Conclusion**: Since a person with AB blood type has both A and B antigens on their RBCs and does not produce any antibodies against these antigens, the correct answer is that there are no antibodies present in the blood plasma of a person with AB blood type.

### Final Answer:
A person with an AB blood type has no anti-A or anti-B antibodies in their blood plasma.
