Double fertilization, a characteristic of angiosperms, results in the formation of:

1.  diploid zygote due to syngamy and triploid primary endosperm cell due to triple fusion
2.  triploid zygote due to triple fusion and diploid primary endosperm cell due to syngamy
3.  diploid zygote due to syngamy and haploid primary endosperm cell as it is formed pre-fertilization
4.  diploid zygote due to syngamy and diploid primary endosperm cell due to triple fusion
