Answer:
Polygenic because a trait is controlled by three different genes
Explanation:
In the given question, the diagram of the question is not found anywhere therefore the question has been answered based on previous knowledge.
The traits of an organism are determined by the sequences of nucleotide present on the DNA called genes. One gene-one protein hypothesis suggests that usually one trait is determined by 2 alleles of a gene but there are few traits which are either determined or influenced by more than one gene.
These traits are known as the polygenic trait as the traits are controlled by more than one or "poly (many) genes" like human eye color, height, and others.
Thus, the selected option is the correct answer.
