Step-by-step solution
Pteridophytes are classified into four classes: Psilopsida ( Psilotum ), Lycopsida ( Selaginella , Lycopodium ), Sphenopsida ( Equisetum ), and Pteropsida ( Dryopteris , Pteris , Adiantum ). Most pteridophytes are homosporous (producing one kind of spore), such as Psilotum , Equisetum , and Dryopteris . However, some genera like Selaginella and Salvinia are heterosporous (producing microspores and megaspores). Therefore, the correct matching is: A. Selaginella - Heterosporous Lycopsida (III) B. Equisetum - Homospor
