The correct option is C A dependent sporophyte
Ferns and moss are both examples of 'primitive plants'. They have not developed all the specialised systems, that modern plants have, although ferns are more highly developed, than mosses. In mosses, sporophytes lack chlorophyll and depend on photosynthetic gametophyte for food, whereas, in ferns, sporophyte stage has true roots, stem and leaves and does not depend on gametophyte.
