A. 1 and 2 only
B. 2 and 3 only
C. 1 and 3 only
D. 1, 2 and 3✓ Correct Answer
💡 Solution & Explanation
All three statements are correct. Tropical wet evergreen forests thrive in high-precipitation zones with dense multilayered canopies. Tropical thorn forests occupy rain shadow areas and dry districts with sparse precipitation where plants develop waxy leaves and thorns to reduce transpiration. Littoral and mangrove forests fringe tidal estuaries and deltas, featuring stilt roots and pneumatophores for gas exchange in anaerobic saline muds. These diverse forest ecosystems are protected under various wildlife sanctuaries and reserve forests.
