The Praja Sammelini was a political party formed in Manipur in 1938. It was led by Hijam Irabot, who was a prominent freedom fighter and social reformer. The party’s main aim was to achieve political reforms in Manipur, such as greater autonomy for the state and the introduction of representative government. The Praja Sammelini played a significant role in the Indian independence movement and in the struggle for democracy in Manipur.

Option c) is incorrect because the Praja Sammelini was not a worker’s rights movement. The party was primarily concerned with political reforms in Manipur, rather than with the specific interests of workers.
Option d) is incorrect because the Praja Sammelini was not a religious revival movement. The party was primarily concerned with political reforms in Manipur, rather than with religious issues.
