Answer

D

Explanation

Bryophyes are non-vascular terrestrial plants of moist habitat in which a multicellular diploid sporophyte lices as a parasite on an independent multicellular haploid gametophyte that develops multicellular jacketed sex organs. True roots are absent, instead rhizoilds occur, which may be unicellular or multicellular. An external layer of water is essential for the swimming of male gametes to the archegonia.
