The correct option is A Haploid vegetative cells and haploid gametangia
A multicellular, filamentous alga exhibits a type of sexual life cycle in which the meiotic division occurs after the formation of zygote. The adult filament of this alga has haploid vegetative cells and haploid gametangia. This type of life cycle is called the haplontic life cycle.
