Select the mismatch. Cycas - Dioecious, Salvinia - Heterosporous, Equisetum - Homosporous, Pinus - Dioecious

Pinus the gymnosperm which possesses both male and female reproductive parts and thus called monoecious. Whereas cycas possesses either male or female reproductive part, Equisetum produces the same type spore (homosporous) and Salvinia produces different types of spores (heterosporous). Thus, the correct answer is option B.
