Solution:

In ABO blood group system is an example of multiple allelism. In which 3 alleles are present as A, B, and O. A and B alleles are dominant while allele O is recessive. Blood group AB can be expressed only in heterozygous condition while blood O is expressed only in homozygous condition. So, If an offspring has an O blood group, then in his parents blood group AB is not possible.
