Solution
The correct option is D Lycopodium
In majority of the pteridophytes all the spores are of similar kinds; such plants are called homosporous and they give rise to bisexual gametophytes.
Lycopodium is a pteridophyte and is homosporous - spores are of same kind that are not differentiated by sex. Selaginella and Salvinia are also pteridophytes but are heterosporous.
Cycas, a gymnosperm, is heterosporous i.e., they produce two kinds of spores - smaller microspores and larger megaspores.
