Answer: Option A
The diploid generation of plant life cycle produce spores.
Explanation:
In plant life cycle, the fusion of two gametes(male and female) result to diploid sporophyte cells.The diploid sporophyte cells undergo meiosis to give haploid spores. The haploid spores undergo mitotic cell divisions to produce a multicellular, haploid gametophyte. The mitotic division of gametophyte will produce gametes.
