Solution
The correct option is C 5
In angiosperms double fertilization takes place; the first fusion is between the egg cell and the sperm cell to form the embryo, the second fusion occurs between the sperm cell and the two polar nuclei to form the endosperm. So a total of 2 sperm nuclei, 1 egg cell nuclei and 2 polar nuclei are involved in double fertilization. Thus, the correct option is C.
