The liverwort or bryophytes thallus is generally a flattened body. Liverworts it is ribbon-shaped and often not vascularized; in leafy liverworts, there is thickened axis with a prominent vascular (hydroid and leptoid) center with flattened leaf-like lobes on either side of the axis. These gametophytes are generally prostrate. The thallus may branch dichotomously. In leafy liverworts, the leaf-like portions are a sheet of cells usually one-cell thick. Those liverwort gametophytes are many cells thick with chambers of filamentous parenchyma cells just under the upper epidermis, and a pad of cortical parenchyma cells beneath. The hydroids are conducting tissues and leptoids carry sugars. Thus the correct answer is option C.
