Since you have type O blood and your mother has type O blood, it is clear that your mother's genotype must be ii, as type O blood is recessive and requires two i alleles. Your father, with type B blood, must carry at least one B allele. However, since you have type O blood, your father must also carry an i allele to pass on to you, making his genotype IBi (simplified here for clarity, not using the complex notation provided in the options). Option C correctly identifies your mother's genotype as ii, and while it attempts to provide a detailed genotype for your father, the specific notation it uses (I^Bi) is not standard and seems to be a placeholder for the concept that he carries one allele for type B blood and one for type O.
