Solution

The correct option is B Diploid
Double fertilization is seen in angiosperms. In this, one sperm fertilizes with the egg cell and forms diploid zygote or oospore while the other sperm fuses with the two haploid polar nuclei and forms a triploid primary endosperm cell. This primary endosperm cell then give rise to nutritive tissue, endosperm.
Thus, the correct answer is option B.
