The equation V G×E > 0 suggests that the interaction between genotype and environment (G×E) is significant, which implies A) genetic variation for phenotypic plasticity, B) that this plasticity is at least partially heritable, and C) that genotypes need to be grown in different environments to accurately estimate narrow sense heritability. Therefore, all of the statements are correct.
