The answer is C. The test cross means that the unknown genotype organism is mated with a homozygous recessive organism("aa"). If the parent organism is homozygous("AA" or "aa"), the offspring will all be the same with the parent(Aa when the parent is "AA". "aa" when the parent is "aa"). So the half of the offspring have the same phenotype means the parent organism is heterozygous. We cannot confirm whether this is polygenic or not by test cross.
