Solution
The correct option is B Psilopsida
Psilopsida are considered as the primitive group. The sporophyte is comprised of the rhizome, aerial branches and small outgrowths. The vascular system is not developed properly. The rhizome is branched and performs the function of root and the outgrowths on stem perform function of photosynthesis. There are sporangia on the stem which produce the spores. Most of these plants are extinct.Thus, the correct answer is option C.
