Result
Your answer: —  Â·  Correct: A
Explanation

Marsilea (often referred to as Marsika), Ferns, and Horse-tails are classic examples of Pteridophyta [2]. Pteridophytes are characterized as vascular cryptogams, meaning they possess well-differentiated plant bodies with roots, stems, and leaves, along with specialized vascular tissues (xylem and phloem) for conduction, yet they do not produce seeds or flowers [1]. Instead, they reproduce via spores. While most pteridophytes are terrestrial and flourish in moist, shady environments, some members like Marsilea are aquatic [1]. Horse-tails (Equisetum) and various fern species are widely distributed globally and represent the first true land plants to develop a conducting system [1]. In contrast, Bryophytes lack vascular tissue, while Gymnosperms and Angiosperms are seed-bearing plants. Therefore, the mentioned plants belong to the Pteridophyta group [2].
