(D) Double fertilization involves two distinct fusion events in the embryo sac:$1$. Syngamy: One male gamete $(n)$ fuses with the egg cell $(n)$ to form a diploid zygote $(2n)$. This involves $2$ nuclei.$2$. Triple fusion: The second male gamete $(n)$ fuses with the two polar nuclei $(n + n)$ to form the primary endosperm nucleus ($PEN$,$3n$). This involves $3$ nuclei.Total nuclei involved = $2$ (syngamy) + $3$ (triple fusion) = $5$ nuclei.
