Solution
The correct option is CEquisetum In contrast to the strobilus of a clubmoss, which is composed of a series of reduced sporophylls (sporangia - bearing leaves), the terminal strobilus of Equisetum is composed of tightly packed whorls of very modified 6 sided structures, called sporangiophores, that look like thick, flat umbrellas. The sporangiophores are attached perpendicular to the axis of the strobilus. Attached to the bottom of each sporangiophore are 5-10 peltate sporangia. When the spores are mature, the strobilus elongates slightly, separating the sporangiophores and allowing the spores to be released. The green, photosynthetic spores of Equisetum bear 4 elaters, which are long strap-like structures that aid in spore dispersal.
