Equisetum spores germinate rapidly after being shed, giving rise to prothallus. Equisetum's protothalli are primarily monoecious, and gametophytes are infrequently observed. Riccia is the most primitive sporophyte among the bryophytes, while Bryopsida is the most advanced. (Polytrichum, Pdgonatum). Sexual reproduction in Volvox is oogamous type. The spores in slime molds, such as Physarum, are haploid, unicellular, typically globose, and have thicker cell walls that are smooth, spiny, or reticulate.

So, "One" is the right response.
