Solution
The correct option is B secondary nucleus
Double fertilisation includes syngamy and triple fusion. In syngamy, the male gamete fuses with the female gamete forming zygote that develops into an embryo. In triple fusion, the male gamete fuses with the diploid secondary nucleus to form a triploid primary endosperm nucleus (PEN) which divides and forms into endosperm.
