Your answer: —  Â·  Correct: C
Explanation

The sexual reproduction process in flowering plants begins with pollination, which is the transfer of pollen grains from the anther to the stigma [3]. Following pollination, the male germ-cell fuses with the female gamete in the ovule, a process known as fertilization [2]. This fusion results in a single-celled zygote [2]. The zygote then undergoes division to grow and develop into an embryo [5]. The embryo is housed within the seed, which contains stored food for development [4]. Finally, when the seed germinates under favorable conditions, it develops into a seedling, which is the young plant that emerges from the seed [1]. Therefore, the correct chronological sequence is pollination, fertilization, division of the zygote, formation of the embryo, and finally the seedling stage.
