Consider the following States:1.Arunachal Pradesh2.Himachal Pradesh3.Mizoram Inwhich of the above States do 'Tropical Wet Evergreen Forests' occur?

1. A

   1 only

   Arunachal Pradesh does have tropical wet evergreen patches in its lower belts, but Mizoram also has them. ‘1 only’ is therefore incomplete. This option is not the key.

2. B

   2 and 3 only

   Himachal Pradesh is largely temperate and alpine Himalayan forest, not tropical wet evergreen. Mizoram does have tropical wet evergreen/semi-evergreen forest, but pairing it with Himachal is wrong. This option is not the key.

3. C

   1 and 3 only

   Tropical wet evergreen forests occur in Arunachal Pradesh (foothills and valleys) and in Mizoram. Himachal Pradesh lies outside that climatic belt. Hence 1 and 3 only is the official key.

4. D

   1, 2 and 3

   Including Himachal Pradesh is incorrect. This option is not the key.

Summary. Official key is (c) 1 and 3 only. Tropical wet evergreen forest needs high rainfall and a short dry season, found in parts of the North-East including Arunachal foothills and Mizoram. Himachal’s forest belts are subtropical pine, temperate oak–conifer and alpine, not tropical wet evergreen. Statement 2 therefore fails. Only Arunachal and Mizoram remain.
