Solution

The correct option is C Polygenes
Multiple alleles, codominance, and incomplete dominance are examples of allelic interactions of the same gene.
A polygenic trait is the one that is governed by more than one gene where dominant alleles of each gene express only a part of trait and the full trait is expressed only in presence of dominant alleles of all multiple genes.
So, the correct answer is D.
