Solution

The correct option is B $A n g i o s p e r m s$
Triple fusion is the fertilization of the two polar nuclei in the embryo sac. It occurs during the double fertilization of angiosperms. While one sperm cell fertilizes the egg cell in the embryo sac, the other sperm cell fertilizes the two polar nuclei found in the central cell. So the correct option is 'Angiosperm'.
