A multicellular, filamentous alga exhibits a type of sexual life cycle in which meiotic division occurs after the formation of the zygote. The adult filament of this alga has:
Haploid vegetative cells and diploid gametangia
Diploid vegetative cells and diploid gametangia
Diploid vegetative cells and haploid gametangia
Haploid vegetative cells and haploid gametangia

Correct option is D)
Many algae show haplontic life cycle. In this case, the dominant phase is the free-living gametophyte.
Sporophytic generation is represented by single-celled zygote. Meiosis in zygote results in the formation of haploid spores, e.g.
So, the correct answer is '
Haploid vegetative cells and haploid gametangia'
