A
IBi
B
IBIB
C
ii
D
IAIB
Explanation: 

Detailed explanation-1: -Combination Genotypes: OO Blood Genotype In order for a person to have type O blood, their genotype must be OO. A person must have inherited an O allele from both parents. If they inherit an A or B from either parent, then they will not be a type O.

Detailed explanation-2: -Two parents with B blood type can produce a child with either B or O blood type. One parent with A and another with B can produce a child with A, B, AB or O blood types.

Detailed explanation-3: -Each parent gives one of their two ABO alleles to the child (3). Mother with AB blood type can either pass the A or B allele to the baby. Likewise, a father with O blood type can only pass O allele to the baby. If both parents belong to the blood group O, the child will also belong to the O blood group.
