    None of those listed and not enough information to give a good answer anyway.

    Rejecting a) and b) right away.  We weren't given the relative frequencies of the alleles in the population.  If one allele has a much higher frequency than the other, then that's the one that's more likely to be passed down.

    Rejecting c) and d).  We weren't told whether these are classic Mendelian or something else such as codominant or incomplete dominance or sex-linked or whatever.
