In which one of the following do male and female gametophytes not have a free-living independent existence?

In gymnosperms (like Cedrus) and angiosperms, the gametophytes are highly reduced and remain permanently within the sporangia borne on the sporophyte. They do not have an independent, free-living existence. In contrast, bryophytes (Funaria, Polytrichum) and pteridophytes (Pteris) have free-living gametophytes.
