Solution

The correct options are
A It is an interaction between two non-allelic genes
C Pleiotropy is an example of intergenic interaction.

Intergenic interaction involves the interaction between two non-allelic genes, which is nothing but genes occupying different loci.
Pleiotropy occurs when one gene influences two or more seemingly unrelated phenotypic traits. Therefore, a mutation in a pleiotropic gene may have an effect on several traits simultaneously due to the gene coding for a product used by a myriad of cells or different targets that have the same signaling function. Therefore, it is an example for intergenic interactions.
Incomplete dominance, however is an example for intragenic interactions. Intragenic interaction is the type of interaction that involves two alleles of a gene present on the same locus of the two homologous chromosomes.
