The correct option is C having multicellular free living gametophyte
Bryophytes have a multicellular, independent and dominant gametophyte on which the sporophyte is dependent for nutrition.
Pteridophytes have independent sporophyte and gametophyte phases. Bryophyte are non-vascular plants and lack vascular tissues, xylem and phloem whereas pteridophytes have vascular tissues. Hence, pteridophytes resemble bryophytes in having free-living gametophytes.
