Which one of the following is the correct sequence during sexual reproduction in Angiosperms ?

In Angiosperms (flowering plants), the sexual reproduction process follows a specific chronological order of development:

• Egg: The process begins with the female gamete (egg cell) located inside the ovule of the flower's ovary.
• Zygote: Upon pollination, a male gamete fuses with the egg cell through a process called syngamy (fertilization), resulting in a diploid zygote.
• Embryo: The zygote then undergoes mitotic cell divisions and differentiation to develop into an embryo, which is the young plant in its earliest stage.
• Seed: Finally, the ovule containing the embryo matures and develops a protective coat, transforming into a seed.

Thus, the correct developmental sequence is Egg → Zygote → Embryo → Seed, as represented in Option A.
