Solution
The correct option is D Primary endospermic nucleus
Primary endosperm nucleus
Triple fusion is the fusion of one of the haploid male gametes, released by the pollen tube into the embryo sac, with the diploid central cell of the embryo sac to form a triploid primary endosperm cell (PEC). The resulting triploid nucleus formed is referred to as the primary endosperm nucleus (PEN). This develops into the endosperm which is a nutritive tissue that nourishes the growing embryo.
Final answer
(c) Primary endospermic nucleus
