In the given diagram life cycle of moss plant ,the stage at which meiosis occurs is:

Explanation

The correct answer is D: (Sporangium). In the life cycle of a moss plant, meiosis occurs in the sporangium. The sporangium is a structure on the sporophyte where meiosis takes place, leading to the formation of haploid spores. These spores eventually germinate and develop into the protonema and subsequently the gametophyte.
