The correct answer is - haploid gametophyte and diploid sporophyte.
Explanation:
All plant life cycle shows alternation of generation. A plant's cycle alternates between haploid and diploid generation. The haploid generation is called gametophytic generation whereas the sporophytic generation.
The multicellular haloid structure of plants called sporophytic generation and these undergo meiotic or reduction division to produce the spores. These spores give rise to a haploid multicellular structure called gametophytic generation.
