Answer
In this scenario, no agglutination will occur because group O blood does not have any antigens (neither A nor B) to react with type A antibodies.
Step 2
antibodies of type A were added to a sample of group B blood.

Answer
Agglutination will not occur as well since group B blood has B antigens but no A antigens to react with type A antibodies.
Step 3

Answer
Similarly, agglutination will not occur here because group A blood has A antigens and no B antigens to react with type B antibodies.
