• A. fusion of two egg cells with two male gmetes
• B. fusion of egg cell twice with male gametes
• C. fusion of one male gamete with the egg cell and the other male gamete with the synergid
• D. fusion of one male gamete with the egg cell and the other male gamete with secondary nucleus

Answer 1

Answer: (D)

fusion of one male gamete with the egg cell and the other male gamete with secondary nucleus

Double fertilization is the process in which one male gamete fused with one egg cell to form the zygote and other male gamete fused with two polar nuclei that form endosperm which provides nutrition to zygote later on.

So the correct option is 'fusion of one male gamete with the egg cell and the other male gamete with secondary nucleus'
