The correct option is C Haplontic
Haplontic life cycle is the primitive type of life cycle characterized by dominant gametophyte and zygotic meiosis. Here, free-living sporophyte absent. The sporophyte generation is represented only by the one-celled zygote, sometimes called as zygospore. The zygote undergoes meiosis to form haploid spores. Each spore germinates (divide mitotically) to form gametophyte. Haplontic life cycle found in many algae, like Volvox, Spirogyra, Ulothrix, Chlamydomonas etc.
