Why did people’s attitude toward British rule change after Jallianwala Bagh?

Correct answer: Because the violent and repressive nature of colonial rule became clear.

The Jallianwala Bagh massacre, in which General Dyer ordered troops to fire on an unarmed gathering in Amritsar in April 1919, exposed the coercive and violent character of colonial rule. The event caused widespread shock and anger and weakened faith in the possibility of receiving justice from the British administration. It did not bring swaraj, restore civil rights, or end political interest. Therefore option A best explains the change in public attitude.
