Solution
The correct option is B Haplontic
Saprophytic generation is represented only by the one-celled zygote. There are no free-living sporophytes. Meiosis in the zygote results in the formation of haploid spores. The haploid spores divide mitotically and form the gametophyte. The dominant, photosynthetic phase in such plants is the free-living gametophyte. This kind of life cycle is termed haplontic. Many algae such as Volvox, Spirogyra and some species of Chlamydomonas represent this pattern.
