Answer:
Option B, One
Explanation:
In a plant life cycle , there is an alternate haploid and diploid sporophytic generation both of which grow by mitotic cell division.
The life cycle starts with diploid sporophyte generation after fertilization through the process of mitotic cell division. This sporophyte generation grows and divide further by meiosis cell division thereby producing diploid spores. The diploid spores grow further by mitotic cell division to produce gametophyte generation. This gametophyte generation grows into eggs and sperm nuclei . The newly formed sperm and egg furtilizes further to produce diploid sporophyte generation. Thus, there occurs only one sporophyte generations between one gametophyte generation and the next time that eggs and sperm are produced
Hence, Option B is correct
