Best Answer

a. ovule

Explanation: With the arrival of pollen on the stigma, the pollen tube enters the ovule and ruptures. One sperm cell fuses with the egg forming the diploid zygote (Syngamy) while the other sperm cell fuses with the polar nuclei forming the endosperm nucleus. The whole process is called double fertilization.
