Concept:
- Two of the options begin with I and two begin with IV, so deciding only which event came first cuts the choices in half.
- The events can then be linked in a cause and effect chain rather than dated one by one.
Step 1: Decide what came first.
The Awadh Kisan Sabha belongs to the peasant mobilisation that grew alongside the Non-Cooperation Movement, at the very start of the 1920s. The Second Round Table Conference belongs to the early 1930s, after the Civil Disobedience Movement had already begun.
So item IV comes first, and options (A) and (B) are out.
Step 2: Compare the two options still standing.
(C) reads IV, III, II, I and (D) reads IV, III, I, II. Both agree on IV first and III second, so only the order of I and II has to be settled.
Step 3: Build the chain from Lahore onwards.
Lahore in December 1929 declared Purna Swaraj. The Civil Disobedience Movement followed in 1930, and it was in that same year that Dr. B.R. Ambedkar organised the Depressed Classes Association.
The Gandhi Irwin Pact then came in March 1931, and only after that did Gandhiji travel to London for the Second Round Table Conference in December 1931.
Step 4: Read the order off the chain.
The Association of 1930 clearly comes before the Conference of 1931, so II precedes I. Option (D) reverses them and fails, while option (C) fits.
Final Answer: (C) IV, III, II, I
