Solution

The correct option is B There is no zygote formation 
In a haplontic life cycle, the sporophytic 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. Many algae such as Volvox, Spirogyra and some species of Chlamydomonas represent this pattern.
