The correct option is A Zygote is located inside the ovule, which is present in the ovary.
The egg is present inside the ovule in the ovary. The pollen reaches up to the egg via pollen tube and fuses with the egg thereby resulting in the formation of a zygote.
So, the zygote is formed inside the ovule in the ovary.
Thus, the correct answer is option (A), 'Zygote is located inside the ovule which is present in the ovary'.
