Solution

The correct option is D Five
Double fertilization is the process of fertilization i.e., the fusion of one male gamete and female ovum and triple fertilization i.e., the fusion of two polar nuclei and another male nuclei occurs at the same time. In this process, three nuclei from the embryo sac and two nuclei from pollen grains are used. Thus, the correct answer is option D.
