Step 1: Understanding geomorphic features.
- Aeolian: Wind action — produces yardangs (elongated ridges carved by wind erosion).
- Glacial: Ice movement — forms drumlins (streamlined hills formed beneath glaciers).
- Fluvial: River processes — form natural levees (raised banks along rivers).
- Coastal: Wave and tidal action — form tombolos (sand/isthmus connecting an island to the mainland).
Step 2: Matching.
P–3 (Aeolian–Yardang), Q–1 (Glacial–Drumlin), R–4 (Fluvial–Natural levee), S–2 (Coastal–Tombolo).
Step 3: Conclusion.
Hence, the correct answer is (C) P–3; Q–1; R–4; S–2.
