The right option is; C. Incomplete Dominance
Incomplete dominance is responsible for Carly's wavy hair.
Incomplete dominance is a type of inheritance pattern in which one allele for a certain trait is not completely dominated, or expressed over its paired allele. Incomplete dominance results in a third phenotype, which is a mixture of the phenotypes inherited from both parent’s alleles. This type of dominance occurs in the multifactorial inheritance of traits such as height, and skin color.
