The correct answer is Option 4- Brahmo Samaj

Raja Ram Mohan Roy founded a reform association known as Brahmo Sabha in 1828, which was later renamed as Brahmo Samaj in 1829.

The Brahmo Samaj was a monotheistic religious and social reform movement in India. It was founded on the principles of monotheism, universalism, and rationalism. The Brahmo Samaj opposed idol worship, the caste system, and other social evils.

The Brahmo Samaj played an important role in the social and religious reform movement in India in the 19th century. It produced many notable leaders, including Debendranath Tagore, Keshab Chandra Sen, and Anandamohan Bose.

The Brahmo Samaj split into several factions after the death of Raja Ram Mohan Roy in 1833. However, it continued to be a force for social and religious reform in India for many years.
