Hint: The kingdom plants are divided into; pteridophytes, bryophytes, gymnosperm, and angiosperm. The basic criteria of classification is the presence of vascular and non-vascular.

Complete answer:
> To solve this question, we have to know about the classification of the plants. The diversity of plants and its classification depends on adaptation. The plants are classified into twelve divisions. These twelve divisions of plants are divided into two groups; the non-vascular plants and the vascular plants. The non-vascular plants have lack of specialized transport tissue while the vascular plants have specialized transport tissue. The sporophytic generation of seedless vascular plants like pterophyta produces sporophytes without fertilization. They produce roots and thick underground stems that are rhizome. This is a food-storage organ. > The breakdown of this food storage organ releases the energy during the growth of the above ground structures. Plants that live anchored to other plants and objects are epiphyte. They are not parasitic on the anchored plants. They come under the seedless vascular plants category. Liverworts are common epiphytes found in tropic or temperate regions. They absorb water from their roots. The flowering plants are also considered as endophytes. They are found in both terrestrial and aquatic condition. They are seed bearing and are termed as angiosperm.
> Now, as asked in the question, the algae are autotrophic in nature and they prepare their own food. Riccia is a liverwort among the three evolutionary lines of non-vascular bryophyte plants that means they do not consist of water conducting tissue. Spirogyra are pond scam, it is developed slimy filamentous masses that are green in colour. They grow in water, during non-availability of sunlight they form large amounts of oxygen. The gnetum is a gymnosperm that consists of pinnate leaf veins and vessels are found in the stem.

Thus, the correct option is ‘a’. A-R, B-S, C-Q, D-P.

Note: Gnetum belongs to genus gymnosperm the sole genus in the family Gnetaceae and order Gnetales. They are evergreen trees, lianas, and shrubs. Like the other gymnosperms they have xylem the vessel elements.
