Correct answer: A. It made freedom a clear goal instead of vague reform
Explanation: The direct answer is option A: the resolution made complete independence a clear national goal instead of a vague demand for reforms. Before this change, many political demands focused on better administration, more representation, or limited self-government. The Lahore Congress of 1929, under Jawaharlal Nehru's presidency, declared Poorna Swaraj, or complete independence, as the objective. The decision was publicly observed through Independence Day on 26 January 1930, before the later Republic Day significance of that date. Option A is correct because it describes this psychological shift from asking the ruler to improve his rule to declaring that Indians should rule themselves. Option B is wrong because the resolution rejected the idea that British rule should continue permanently. Option C is wrong because the national movement became broader and more united, not merely provincial. Option D is wrong because Congress continued to lead the movement; it was not ended. Memory cue: Poorna Swaraj means the complete goal—freedom, not merely reform.
