Vedclass · Answer

(C) In angiosperms,the process of double fertilization involves the fusion of one male gamete with two polar nuclei to form the Primary Endosperm Nucleus $(PEN)$.Since the male gamete is haploid $(n)$ and the two polar nuclei are also haploid $(n + n)$,their fusion results in a triploid $(3n)$ structure.Therefore,the ploidy level of $PEN$ is $3n$.
