Match List I with List II and select the correct answer using the code given below the lists: List – I A) Tropical forest B) Conifer forest C) Mangroves D) Deciduous forest List – II a) Sunderbans b) Himachal Pradesh c) Rajasthan d) Silent Valley Codes:

The correct answer is D. Tropical forest matches Silent Valley (d), a tropical evergreen rainforest in Palakkad, Kerala. Conifer forest matches Himachal Pradesh (b), where pine, deodar and fir dominate the temperate hill slopes. Mangroves match the Sundarbans (a), the tidal delta forest of the Ganga-Brahmaputra-Meghna system. Deciduous forest matches Rajasthan (c), where dry deciduous and thorn formations are found in the semi-arid belt.

• Option A is wrong because it places tropical forest in the Sundarbans. The Sundarbans is a mangrove ecosystem, not a tropical evergreen forest.
• Option B is wrong on two counts. Tropical forest is not Himachal Pradesh, and conifers are not the Sundarbans.
• Option C is wrong because mangroves are not in Himachal Pradesh and tropical forest is not in the Sundarbans.

The core concept is the Champion and Seth classification of Indian forest types and their regional distribution. For Mains, this links to biodiversity hotspots, the Western Ghats and Sundarbans as ecologically sensitive zones, and the Forest (Conservation) Act, 1980.

Trap: Aspirants often place Silent Valley under conifers or hill forests because it is a famous protected area. It is a tropical evergreen forest in Kerala.
