Explanation
The correct option is C: 1919.
The Rowlatt Act was passed by the Imperial Legislative Council on 18 March 1919.
It was a law that gave the British government and police the power to arrest and detain anyone suspected of seditious activities without a trial.
It was also known as the Anarchical and Revolutionary Crimes Act or the Black Act. The Rowlatt Act was opposed by many Indian leaders, including Mahatma Gandhi, who launched the Rowlatt Satyagraha to protest against it. The Rowlatt Act was repealed in 1922.
