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

Correct Option

The states labelled in the map are identified as follows:

• 1: Odisha
• 2: Manipur
• 3: Mizoram
• 4: Arunachal Pradesh

Based on the 2001 Census data, the approximate percentage of Scheduled Tribe (ST) population to the total population for these states is:

• Mizoram (3): 94.75%
• Arunachal Pradesh (4): 63.66%
• Manipur (2): 34.4%
• Odisha (1): 22.21%

Arranging these states in descending order of their ST population percentage yields the sequence: Mizoram (3) > Arunachal Pradesh (4) > Manipur (2) > Odisha (1). Therefore, the correct sequence is 3, 4, 2, 1.

Incorrect Options

Options (a), (c), and (d) do not accurately represent the descending order of the percentage of Scheduled Tribe population to the total population for the identified states. These options incorrectly sequence the relative proportions of ST populations in Odisha, Manipur, Mizoram, and Arunachal Pradesh according to census data.
