Vedclass · Answer

(B) Triple fusion is a key event in the process of double fertilization in angiosperms.It involves the fusion of one male gamete $(n)$ with two polar nuclei (or a secondary nucleus formed by the fusion of two polar nuclei,each $n$) present in the central cell.Since the male gamete is haploid $(n)$ and the two polar nuclei are also haploid $(n + n)$,their fusion results in the formation of a triploid $(3n)$ primary endosperm nucleus $(PEN)$.Therefore,it is the fusion of three haploid nuclei.
