This is a significant evolutionary adaptation to protect the developing gametes from desiccation. Option $A$ is incorrect because in Bryophytes,the sporophyte is dependent on the gametophyte. Option $C$ is incorrect because the sporophyte is dominant only in Pteridophytes,not in Bryophytes. Option $D$ is incorrect because the gametophyte in Pteridophytes is usually a small,independent prothallus,not necessarily thalloid.
