Concept:
- All four events belong to the national movement between 1920 and 1931, so each has to be given a year before they can be sorted.
- Two belong to the peasant and depressed class movements and two to the mainstream Congress programme.
Step 1: Date item IV, the Awadh Kisan Sabha.
Jawaharlal Nehru, Baba Ramchandra and a few others set up the Oudh Kisan Sabha in
October 1920. Within a month it had over three hundred branches in the villages around the region.
This is the earliest of the four.
Step 2: Date item III, the Lahore session of the Congress.
The Lahore session met in
December 1929 under the presidency of Jawaharlal Nehru and formalised the demand for
Purna Swaraj, or full independence.
Step 3: Date item II, the Depressed Classes Association.
Dr. B.R. Ambedkar organised the dalits into the Depressed Classes Association in
1930.
Step 4: Date item I, the Second Round Table Conference.
Gandhiji went to London for the Second Round Table Conference in
December 1931, after the Gandhi Irwin Pact of March that year.
Step 5: Sort the years.
1920 → 1929 → 1930 → 1931, which is IV → III → II → I. This matches option (C).
Final Answer: (C) IV, III, II, I
