Egg, Zygote and Endosperm nucleus

C
Nucellus, Endosperm and Egg

D
Antipodals, synergids and Nucellus

Solution

The correct option is A Egg, Zygote and Endosperm nucleus
Angiosperms or flowering plants are characterized by the process of double fertilization. It involves the fusion of one male gamete (n) with egg (n) resulting in the formation of a diploid zygote (2n). The other male gamete (n) fuses with a secondary nucleus (2n) to form a triploid endosperm (3n) respectively. Thus the correct answer is option A.
