    B: ss

    Explanation:

    Since straight hair is dominant it would be a capital S and curly would be a lower case s. If a straight hair gene was in the genotype it would block out the curly hair, so the only way to have curly hair would be ss.

    B: ss

    Explanation:

    In order for the recessive curly-haired gene (s) to be expressed in the phenotype, there needs to be no dominant straight haired gene (S) in the genotype.
