Solution
The correct option is A Lycopsida
In Lycopsida, the sporophyte is differentiated into stem, roots and leaves. The leaves are microphyllous and with a single vein. The vascular strands or steles may be protostelic, siphonostele or polystelic. The leaf-gaps are always absent, sporophylls produce a single sporangium on the adaxial side near its base. The sporophylls are borne in strobili. They are homosporous or heterosporous. The antherozoids are biflagellate or multiciliated.Therefore, the correct answer is option A.
