Solution

The correct option is B Triple fusion
In flowering plants, the process of double fertilization involves two types of fusion - syngamy and triple fusion. When one male gamete fuses with an egg to form a zygote, it is termed as syngamy. The other male gamete fuses with the two polar nuclei, termed as triple fusion, which results in the formation of a triploid endosperm.
