Solution

The correct option is C are formed by fusion of gametes
Double fertilization in angiosperms triggers the transformation of ovule into a seed. The zygote delvelops into an embryo. In double fertilization, one male gamete fuses with the egg to form the diploid zygote, the other male gamete fuses with the two polar nuclei to form the triploid primary endosperm nucleus.
So, the correct answer is 'Are formed by fusion of gametes'.
