Solution
The correct option is A Pteridophyta
The plant life cycle includes alternation of generations, wherein two generations - a haploid gametophytic one alternates with a diploid sporophytic one to complete a life cycle. The gametophytes produce sporophytes, and sporophytes produce gametophytes. While in some species the gametohytes and sporophytes are isomorphic and inistinguishable from each other, in case of Pteridophytes especially ferns the two forms are separate, free-living and
independent of each other, giving rise to heteromorphic alternation of generations. Hence the correct option is A.
