Hint:Pteridophytes are a phylum of plants. Those having xylem and phloem tissues. They are found in the tropics with only about 600 species adapted for life in temperate climates.

Complete answer : Pteridophytes are the vascular plants that are reproduced by releasing spores rather than seeds and they include the highly diverse true ferns and other graceful forest dwelling plants. There are about 11000 different species of Pteridophytes which makes them most diverse and plants. Pteridophytes range greatly in size. There are tiny floating ferns used as “green fertilisers” in rich paddies. Pteridophytes are also called as Vascular Cryptogams because they produce neither flowers nor seeds and also because of the conduction tissues which are called as vascular bundles. Pteridophytes are said to be non-seed bearing plants which reproduce only by production of spores. They grow in moist soil.
Pteridophytes include ferns, horsetail, clubmosses, spikemosses etc. They do not form monophyletic groups because ferns and horsetails are more closely related to seed plants rather than lycophytes.

Thus the correct answer is option C i.e., Vascular Cryptogams

Notes:Ferns are a group of around 10000 vascular plants that first evolved around 360 millions years ago. Ferns can be used to illustrate the life cycle states common to all Pteridophytes. There are early free-sporing tracheophytes – pteridophytes or cryptogams – and seed plants.
