Concept:
- The passage names two cities and two dates, so the safe method is to pair each city with the event that happened there before answering.
- Once the pairs are set, the answer cannot be confused.
Step 1: Pair the first city with its event.
Wardha, 14 July 1942, is where the Congress Working Committee passed the Quit India resolution. This was the drafting stage of the movement.
Step 2: Pair the second city with its event.
Bombay, 8 August 1942, is where the All India Congress Committee endorsed that resolution. This was the launching stage, the moment the movement went public.
Step 3: Decide which stage the speech belongs to.
A call to the whole nation to do or die suits the launch of a mass struggle, not a committee drafting session. The source confirms it by saying the speech came on the occasion of the Bombay endorsement.
Final Answer: The Do or Die speech was delivered in Bombay on 8 August 1942.
