As one moves from thallophyta → Bryophyta → Pteridophyta → Gymnosperm → Angiosperms, there is reduction in the gametophyte and elaboration of sporophyte.

Question

Accepted Answer

Both statements are correct.. In plant evolution, the gametophyte becomes increasingly reduced from thallophytes to angiosperms, while the sporophyte becomes more complex and dominant. Mosses (bryophytes) have a relatively large, independent gametophyte compared with later groups, so both statements are true.
