Detailed explanation-1: -In most cases, an O parent and an AB parent will have only A or B kids. I added a table at the end of this answer that has all blood type combinations for two parents plus the possible blood types for their children. Exceptions to these rules are extremely rare.
Detailed explanation-2: -F1 generation phenotypic ratio = 1 A group : 2 AB group : 1 B group; hence, parents with AB blood group can have a child with A, AB and B blood group. Correct option is “B".
Detailed explanation-3: -One parent with A and another with B can produce a child with A, B, AB or O blood types. If one parent has A and another has AB, they can either produce a child with A, B or AB blood types. If one parent has A and another has O, they can either produce a child with A or O blood types.
Detailed explanation-4: -Two B blood group parents can give their child either B or O blood group. One parent with A and another with B will give their child either A, B, AB or O groups. One parent with A and another with AB will give their child either A, B or AB groups.
