The correct option is D Bryophytes
Bryophytes are non-vascular terrestrial plantsof moist habitat in
which a multicellular diploid sporophyte lives as a parasite on an
independent multicellular haploid gametophyte that develops
multicellular jacketed sex organs. True roots are absent, instead
rhizoids occur, which may be unicellular or multicellular. An external
layer of water is essential for the swimming of male gametes to the
archegonia. So, the correct answer is 'Bryophytes'.
