Answer:

C. blue  

Explanation:

In genetics, homo-zygous individuals are those individuals that have the same allele form (i.e., the same allele) for a given gene/locus, whereas heterozygous individuals have different alleles for that gene/locus. Complete dominance is a form of dominance that occurs when the allele that is dominant for a given gene/locus completely masks the effects of the recessive allele in a heterozygous individual. In this case, individuals that are heterozygous (genotype Ff) exhibit a dominant flower-blue phenotype because the dominant 'F' allele completely masks the effect of the recessive 'f'  allele; therefore producing a phenotypic ratio of 3:1 in the offspring of a mating between two heterozygous individuals for this single trait.
