The correct option is C Pogonatum
Bryophytes are broadly categorised into liverworts, mosses and hornworts.
Pogonatum is a class of moss in which sporophyte is a partial parasite gametophyte. Mosses are higher bryophytes. Their sporophyte is although remain attached on gametophyte, but at maturity it become green at some regions, so become photosynthetic. Thus it become partially dependent and partially independent to gametophyte. Thus it act as partially parasitic on the gametophyte.
While Marchantia, Porella and Riccia belongs to liverworts
