Solution
The correct option is B Spore mother cells The spore mother cells are produced within the sporogonium. these are diploid (2n) and represent the last stage of the sporophyte generation. The spore mother cells undergo the reduction division (meiosis) and the tetrads of the haploid (n) spores are formed. The spores represent the beginning of the gametophyte generation.
