According to the table, the child with blood type AB has to have parents with blood types A and B since AB is a combination of A and B. Therefore, the couple with blood types A and B are the actual parents of the child with blood type AB. The other two babies have blood types O and B, which cannot be produced with a parent with blood type A and B.
