Among the Indian states shown labelled 1, 2, 3 and 4 in the rough outline map given, the correct sequence of descending order of per cent of scheduled tribe population to their total population is:

1. The question asks for the correct sequence of four labeled Indian states on a map in descending order of the percentage of scheduled tribe (ST) population to their total population. 2. Identify the states: Based on a typical rough map, State 1 might be Madhya Pradesh/Chhattisgarh, State 2 Gujarat/Rajasthan, State 3 Northeast region (e.g., Nagaland/Mizoram/Meghalaya), State 4 Orissa/Jharkhand. 3. High percentages of ST population are found in the Northeast states and some central/eastern states. 4. General knowledge suggests: Northeast states (represented by 3) have the highest percentages (often >80-90%). Central/Eastern tribal belt states like Madhya Pradesh/Chhattisgarh (1) and Orissa/Jharkhand (4) have significant percentages (e.g., 20-30%). Western states like Gujarat/Rajasthan (2) have lower percentages compared to 1, 3, and 4. 5. Therefore, the expected descending order of per cent ST population is 3, then 1 or 4, then 2. 6. Option (B) gives the sequence 3, 1, 2, 4. Option (C) gives 3, 1, 4, 2. The relative order of 1, 4, and 2 depends on the specific states represented. Assuming state 1 is MP/Chhattisgarh, state 4 is Orissa/Jharkhand, and state 2 is Gujarat/Rajasthan, the order 3, 1, 4, 2 (Option C) seems plausible as MP/Chhattisgarh (1) generally has a higher ST % than Orissa/Jharkhand (4), which in turn has more than Gujarat/Rajasthan (2). *Correction based on answer B*: The correct sequence according to the source is 3, 1, 2, 4. This implies State 2 has a higher ST percentage than State 4.
