The answer is; C
Rhizoids are analogous to roots in vascular plants. They anchor the gametophyte of the moss into the substrate. The rhizoid is also significant in absorbing nutrient from the substrate just like roots. While roots of vascular plants are multicellular, rhizoids may be unicellular or multicellular. Unlike in roots where water is absorbed and passes through the roots up the plant, in rhizoids, water is carried by capillary action in between the rhizoid threads.
