Answer:

C

Explanation:

Father/mother must each donate a blood gene to the child. Father must have a genotype of ii because O blood is recessive. Thus, the kid must have one O type gene. However, the kid has A type blood overall, so the kid must have an A (dominant) gene as well. Thus, the answer is IAi.
