Correct Answer: (A) (III), (I), (II), (IV)

Step 1 - Start with the origin of the term:

Statement (III) introduces the subject by telling us that the word 'Adivasi' was coined in the 1930s as part of a struggle. This is the natural starting point.

Step 2 - Trace the background of the problem:

Statement (I) then explains where the extraction of resources from tribal areas began, that is, under the British Government.

Step 3 - Move to the recent phase:

Statement (II) shows how the same process became far stronger after the economic liberalisation policies of the 1990s.

Step 4 - End with the outcome:

Statement (IV) gives the achievement of the Adivasi movements, the creation of Jharkhand and Chhattisgarh in the year 2000.

Step 5 - Eliminate the rest:

Option (B) places the 1990s before the 1930s, option (C) begins with the year 2000, and option (D) ends with British rule. All three break the sequence.

Hence, option (A) is correct.
