All the following options regarding blood transfusion is incorrect, except

Options

A. The recipient plasma should not contain antigens against antibodies present in donor plasma.
B. The donor RBCs should not contain antibodies against an antigen in recipient plasma.
C. The recipient plasma should not contain antibodies against donor RBCs antigens.
D. The recipient RBCs should not have antigens found on donor RBCs.

Answer

To solve the question regarding blood transfusion, we need to analyze the statements provided and determine which one is correct. The question states that all options regarding blood transfusion are incorrect except for one.

### Step-by-Step Solution:

1. **Understand the Basics of Blood Transfusion**:
- Blood transfusion involves transferring blood from a donor to a recipient.
- The key factors in successful blood transfusion are the antigens present on the red blood cells (RBCs) of the donor and the antibodies present in the plasma of the recipient.

2. **Identify the Importance of Antigen-Antibody Compatibility**:
- For a successful blood transfusion, the antigens on the donor's RBCs must not match the antibodies in the recipient's plasma. If they do match, it can lead to agglutination (clumping) of the RBCs, which is harmful.

3. **Examine Each Statement**:
- **Option 1**: "Recipient plasma should not contain antibodies."
- This is incorrect because the recipient's plasma must contain antibodies to identify foreign antigens.

- **Option 2**: "Donor RBCs should not contain antibodies."
- This is also incorrect because the antibodies are present in the plasma, not on the RBCs themselves.

- **Option 3**: "Recipient plasma should not contain antibodies against donor RBC."
- This statement is correct. The recipient's plasma must not have antibodies that can react with the donor's RBC antigens.

- **Option 4**: "Recipient RBCs should not have antigens found on donor's RBC."
- This statement is incorrect because the recipient's RBCs can have the same antigens as the donor's RBCs, which can lead to complications.

4. **Conclusion**:
- The only correct statement among the options provided is Option 3: "Recipient plasma should not contain antibodies against donor RBC."

### Final Answer:
The correct statement regarding blood transfusion is: **"Recipient plasma should not contain antibodies against donor RBC."**
