Which of the following events occurred as an after-effect of the Jallianwala Bagh Massacre (13th April 1919)?

Hunter Commission was appointed by the British Government

The correct answer is Option 3- Hunter Commission was appointed by the British Government

Among the options provided, the event that occurred as an after-effect of the Jallianwala Bagh Massacre (13th April 1919) is: Hunter Commission was appointed by the British Government.

The Hunter Commission, officially known as the "The Indian Statutory Commission," was appointed by the British Government to investigate the Jallianwala Bagh Massacre and the circumstances leading up to it. It was headed by the British judge Sir William Hunter.
The Hunter Commission largely exonerated Brigadier General Reginald Dyer, who ordered the troops to open fire on the unarmed civilians at Jallianwala Bagh. The commission's report acknowledged the brutality of the massacre but justified Dyer's actions as a response to maintaining public order.
Overall, the Hunter Commission's outcome did not bring about the desired justice for the victims of the massacre and further eroded the trust between the Indian people and British authorities.
