A. W-Ulothrix, X-Marsilea, Y-Selaginella, Z-Cycas
B. W-Riccia, X-Marsilea, Y-Cycas, Z-Ipomoea
C. W-Lycopodium, X-Marchantia, Y-Pinus, Z-Ipomoea
D. W-Spirogyra, X-Dryopteris, Y-Funaria, Z-Pinus

Answer

B

Explanation

According to the given flow chart W, X, Y and Z could be bryophyte, pteridophyte, gymnosperm and angiosperm respectively. Riccia is a bryophyte and is a non-vascular plant, i.e., xylem and phloem are absent. Marsilea is a pteridophyte, possessing vascular system but it does not produce flowers and is seedless. Cycas is a gymnosperm that produces seeds which are naked, i.e., not enclosed within fruits. Ipomoea is an angiosperm. It is highly evolved plant with seeds protected inside fruits.
