Correct answer: CThe direct answer is C, 1937. The Government of India Act 1935 introduced provincial autonomy and provided the constitutional framework for provincial elections. The elections were held in 1937. After the results, the Indian National Congress formed ministries in several provinces, although the political situation differed from province to province. Option A, 1935, is wrong because that is the year of the Act itself, not the year in which these provincial elections were held. Option B, 1936, is wrong because preparations and political activity occurred around that period, but the elections are dated 1937. Option C is correct because the provincial elections took place in 1937. Option D, 1939, is wrong for the election date; in 1939 Congress ministries resigned after the Viceroy involved India in the Second World War without consulting Indian leaders. The useful sequence is Act in 1935, elections in 1937, Congress ministries, and resignations in 1939. Memory cue: 35 made the framework, 37 held the elections, 39 brought resignations.
