The right answer is A. multiple alleles.

The multiallelic genes contribute to the study of polymorphism and genetic variability of individuals as well as populations.

In multi-allelic genes, individuals are differentiated by several alleles that exist in several forms.

For example: in a certain region of the genome there may be a single nucleotide polymorphism (SNP), one can find either an adenine or a guanine (bi-allelic).
