Vedclass · Answer

(B) In angiosperms,the process of double fertilization occurs. One male gamete $(n)$ fuses with the two polar nuclei $(n + n)$ to form the primary endosperm nucleus $(PEN)$. This process is known as triple fusion. Since the $PEN$ is formed by the fusion of three haploid nuclei,it is triploid $(3n)$. Therefore,the endosperm developed from the $PEN$ is triploid $(3n)$.
