    The correct answer is A) Freckles

    Explanation:

    Freckles is a genetic disorder that is controlled by the MC1R gene which is signified by the overproduction of melanin pigment on body and face. Freckles is controlled by the dominant allele so it show dominant inheritance pattern.

    Therefore if an individual has even one freckle allele then this disorder will be seen in the phenotype. A person will not have freckles if it has both the recessive allele i. e., ff.

    Therefore an individual who is heterozygous for freckles would have freckle phenotype because it contain one dominant allele for freckles which will express in the phenotype. So the right answer is A.
