(A) is the right answer.
1. haplontic life cycle : Sporophytic generation is represented only by the one-celled zygote. There are no free-living sporophytes. 2.diplontic life cycle : the diploid sporophyte is the dominant, photosynthetic, independent phase of the plant. 3. Haplo-diplontic life cycle : Bryophytes and pteridophytes exhibit an intermediate condition; both phases are multicellular.But they differ in their dominant phases. bryophytes: short- lived multicelluler sporophyte totally or partially dependent on the gametophyte for its anchorage and nutrition. pteridophytes : diploid sporophyte is represented by a dominant, independent, photosynthetic, vascular plant body
