what is the possible genotypes will produce type B blood?

In humans, there are four types of blood: type A, type B, type, AB and type O. The alleles A and B are codominant to each other and the O alleles is recessive to both A and B alleles. So a person with the genotype AA or AO will have A blood.

A. what is the possible genotypes will produce type B blood? B. what is the only genotype that will produce type O blood? C. what is the only genotype that will produce type AB blood?
