The correct answer is Lala Hardayal .

The founder of the Gadar Party was Lala Hardayal and Sohan Singh Bhakna. The party was established in 1913 in the United States, primarily by Punjabi Indian immigrants. The name “Gadar” means “revolt” or “mutiny” in Punjabi, and the party’s ultimate goal was to overthrow British rule in India.

Lala Hardayal was a Punjabi scholar and writer who had been exiled from India due to his nationalist activities. He traveled to the United States and became involved in the Ghadar Movement, which aimed to use Indian soldiers in the British Army to rebel against British rule.

In 1913, Lala Hardayal and other Indian nationalists established the Gadar Party in San Francisco, California. The party published a newspaper called The Gadar, which advocated for Indian independence and called for an armed revolution against the British. The party also organized Indian immigrants in the United States and Canada to support the movement for Indian independence.

During World War I, the Gadar Party attempted to launch an armed uprising against British rule in India with the help of German and Ottoman forces. The plot was uncovered, and many Gadar Party members were arrested and imprisoned. Despite its limited success, the Gadar Party played an important role in the Indian independence movement, and its legacy is still remembered today.
