Fertilisation takes place in presence of water
Zygote undergoes meiosis to produce sporophyte
Gametophytic phase is dominant in life cycle
Sporophyte is physiologically dependent on gametophyte
After the process of fertilisation a diploid zygote is formed which undergoes many rounds of mitosis and give rise to a diploid multicellular sporophyte. The specialised cells of the sporophyte further undergoing meiosis form haploid spores. These spores develop into gametophytes. So, the correct answer is option B. The statement 'Zygote undergoes meiosis to produce sporophyte' is incorrect. The zygote undergoes mitosis to produce the sporophyte. Meiosis occurs in the sporophyte to produce spores.
