Answer:

Ao and Bo

Step-by-step explanation:

Based on the possible genotypes for the blood types, you are given, the presence of the possibility being "oo" means that both of the two parents must have the o in their blood type even since they would receive one letter from each parent, this means it cannot be the first, third, or fourth choice due to the lack of an o in one of the two parent genotypes.
