(A) Double fertilization is a characteristic feature of angiosperms.It involves two fusion events:$1$. Syngamy: One male gamete fuses with the egg cell to form a diploid zygote $(2n)$.$2$. Triple fusion: The second male gamete fuses with the two polar nuclei (or the secondary nucleus) to form a primary endosperm nucleus $(PEN)$,which is triploid $(3n)$.Thus,a total of $3$ gametes are involved: two male gametes and one egg cell (the polar nuclei are considered part of the female gametophyte structure,but the fusion involves $3$ haploid nuclei in total,specifically $2$ male gametes and $1$ egg cell for syngamy,and $1$ male gamete and $2$ polar nuclei for triple fusion). However,in terms of distinct gametic cells participating,there are $2$ male gametes and $1$ egg cell,totaling $3$ gametes.

The number of gametes taking part in double fertilization is $:-$
