The correct option is C Both A and B
In diplohaplontic lifecycle, a diploid (2n) sporophyte undergoes meiosis to
produce haploid (n) spores or reproductive cells. These haploid
cells then undergo mitosis to produce a gametophyte(n). which further produces
haploid gametes that come together to form a diploid zygotic sporophyte. Meiosis occurs during the gamete formation. This type of lifecycle is seen in all sexually reproducing organisms e.g., kingdoms Animalia and Plantae exhibit gametic meiosis.
