Solution

The correct option is B Fusion of two haploid gametes, haploid spores
Most plants exhibit alternation of generations in their life cycle. These plants have a diploid sporophytic phase that produces the haploid spores which form the gametophyte. This haploid gametophyte produces haploid gametes which then fuse to form the diploid sporophyte and that further develops into a plant.
Thus, the correct answer is option B.
