How did the Rowlatt Act and Jallianwala Bagh create the background for the Non-Cooperation Movement?

Correct answer: They increased public anger against colonial repression

The Rowlatt Act allowed detention without trial and was widely seen as an attack on civil liberties. Public protests against it were followed by the Jallianwala Bagh massacre, where peaceful people were fired upon. These events exposed the repressive nature of colonial rule and destroyed faith in British justice among many Indians. The resulting anger and sense of injustice helped prepare people to withdraw cooperation. Thus, option A is correct; the other options contradict the historical consequences.
