Solution
The correct option is B 50%
Parents of homozygous recessive * parents of heterozygous In this case, 50% of offsprings will have O blood group. Each of the parents donates one of their two alleles to their offspring if any one parent has O blood group then the offspring has 50% chances of getting O blood group.So, the correct option is '50%'.
