You are shown caterpillars of the moth Nemoria arizonaria.The caterpillars belong to the same species,but some of the caterpillars that were collected from oak flowers resemble oak flowers,while caterpillars collected from oak twigs resemble oak twigs.What is the most plausible explanation for the phenotypic variation?

A)Some of the caterpillars had a mutation that changed the genotype and phenotype.
B)The phenotypic variation appears to be influenced by the environment/diet.
C)Variation among individuals in this species is common, but over time one phenotype will outcompete the other phenotype.
D)The variation is due to heterozygote protection.
E)More data needs to be collected.
