Question

Given below are two statements:
Statement I : During a blood group test, agglutination occurs with both Anti sera A and B.
Statement II : Blood group is AB.
In the light of the above statements, choose the most appropriate answer from the options given below:

• A. Both Statement I and Statement II are correct
• B. Both Statement I and Statement II are incorrect
• C. Statement I is correct but Statement II is incorrect
• D. Statement I is incorrect but Statement II is correct

Hint:

AB group shows agglutination with both Anti-A and Anti-B sera.

Answer 1

The Correct Option is A

In blood grouping tests, agglutination with Anti-A serum indicates the presence of A antigen, while agglutination with Anti-B serum indicates the presence of B antigen.
If both reactions are positive, the person’s blood group is AB.
Therefore, Statement I is correct as agglutination occurs with both sera.
Statement II is also correct because this pattern identifies blood group AB.
So, both statements are true and consistent.
