• A. Two polar nuclei & one male gamete
• B. One polar nuclei & one male gamete
• C. Ovum and male gamete
• D. Two polar nuclei & two male gametes

Answer 1

The correct option is A Two polar nuclei & one male gamete

Double fertilization usually occurs in angiosperms, and it involves the formation of the embryo as well as the endosperm at the same time. During the process of double fertilization, a male gamete and two polar nuclei join together to produce a triploid nucleus that further develops to form the endosperm.

So, the correct answer 'Two polar nuclei & one male gamete'.
