The correct option is A Antirrhinum
In the snapdragon, Antirrhinum majus, a cross between a homozygous white-flowered plant (WW) and a homozygous red-flowered plant (ww)will produce offspring with pink flowers (Ww).This type of relationship between alleles, with a heterozygote phenotype intermediate between the two homozygote phenotypes, is called incomplete dominance.
So, here option (A) is correct.
