Step 1: Understanding the Question:
The question requires matching plant taxonomical groups listed in LIST-I with their corresponding genus examples in LIST-II.
Step 2: Key Formula or Approach:
Systematically evaluate each plant category and match it to its correct representative organism:
• Moss (Bryophyte): Sphagnum (Peat moss).
• Pteridophyte: Selaginella (Spike moss/heterosporous pteridophyte).
• Gymnosperm: Sequoia (Giant redwood tree).
• Angiosperm: Wolffia (Smallest flowering plant/duckweed).
Step 3: Detailed Explation:
• A. Moss $\to$ IV. Sphagnum: Sphagnum is a bryophyte belonging to class Bryopsida (mosses), known for building peat bogs due to its high water-retention capacity.
• B. Pteridophyte $\to$ III. Selaginella: Selaginella is a vascular seedless plant classified under Lycopsida (pteridophyte) demonstrating heterospory.
• C. Gymnosperm $\to$ II. Sequoia: Sequoia sempervirens is a giant coniferous gymnosperm tree species producing exposed seeds.
• D. Angiosperm $\to$ I. Wolffia: Wolffia is the smallest known genus of flowering vascular plants (angiosperms).
Step 4: Fil Answer:
The correct matching sequence is A-IV, B-III, C-II, D-I.
