The correct answer is: a) Anti-Rowlatt Act protests.
Sardar Ajit Singh was a prominent figure in the Anti-Rowlatt Act protests. He was a freedom fighter who fought against British rule in India. He was also the uncle of Bhagat Singh, another famous freedom fighter.
The Rowlatt Act was a law passed by the British government in 1919. The law gave the government the power to arrest and detain people without trial. This law was very unpopular with the Indian people, and there were widespread protests against it. Sardar Ajit Singh was one of the leaders of these protests.
He was arrested and imprisoned for his role in the protests. However, he continued to fight for Indian independence after his release from prison. He was a key figure in the Ghadar Party, which was a revolutionary organization that fought against British rule.
