(C) Heterospory is the production of two types of spores,microspores and megaspores. $Selaginella$ is a pteridophyte that is heterosporous. $Pinus$ and $Cycas$ are gymnosperms,and all gymnosperms are heterosporous. $Pteridium$ (a type of fern) is homosporous,meaning it produces only one type of spore. Therefore,$Pteridium$ is not heterosporous.
