However, it was Montagu's statement in 1917 which talked of Swaraj and the Montagu Chelmsford reforms or the Government of India Act, 1919 that calmed the revolutionary activity to a certain extent. ● Statement 3 is incorrect: The Khilafat issue arose post the end of the World War I after the Treaty of Sevres completely dismembered Turkey, which was the seat of Khalifa, recognized by all the Muslims throughout the world. This had no role in the decline of revolutionary activism. ● Statement 4 is correct: The release of the political prisoners arrested because of the provisions of the Defense of India Act, 1915 also calmed the atmosphere to a great extent and suppressed the revolutionary activities. ● Statement 5 is incorrect: There were numerous mutinies witnessed at several places during the revolutionary activism.

They were a part of revolutionary activism and were in no way related to its decline.
