The correct answer to the question is option 1: All India Home Rule League.

The All India Home Rule League was formed by Annie Besant and Bal Gangadhar Tilak in 1916, with the aim of obtaining self-government for India within the British Empire. However, in 1920, the organization changed its name to "Swarajya Sabha" to reflect its emphasis on complete independence from British rule.

The term "Swarajya" means self-rule or self-governance in Sanskrit, and was a key concept in the Indian independence movement. The renaming of the organization was part of a broader shift towards more radical demands for independence, as opposed to the earlier focus on obtaining limited self-government within the British Empire.

The Swarajya Sabha played an important role in mobilizing support for the independence movement, particularly in the years leading up to the Non-Cooperation Movement of 1920-22. The organization held public meetings, organized protests and strikes, and advocated for a wide range of social and political reforms.

Overall, the renaming of the All India Home Rule League to Swarajya Sabha was a significant moment in the Indian independence movement, reflecting a growing demand for full independence from British rule and a rejection of the earlier strategy of seeking limited self-government within the Empire.
