The correct option is A True
The main plant body of the bryophyte is haploid. It produces gametes, hence is called a gametophyte. The sporophyte in bryophytes is a multicellular body that is not free-living but attached to the photosynthetic gametophyte and derives nourishment from it. In pteridophytes too, the gametophyte is free-living, mostly photosynthetic thalloid, called prothallus.
