Solution
The correct option is B Gymnosperms
Heterospory is the production of spores of two different sizes and sexes by the sporophytes of land plants. Gymnosperms, like all vascular plants, have a sporophyte-dominant life cycle. The gametophyte is relatively short-lived. Two spore types, microspores and megaspores, are typically produced in pollen cones or ovulate cones, respectively.
Archegoniatae was a higher taxonomic term that indicated those embryophytes having a female sexual organ in the form of an archegonium.
In gymnosperm megagametophytes develop from megaspores and are retained within the ovule. They typically produce multiple archegonia.
Hence the correct option is B.
