The correct option is C 1828
In August 1828, Raja Ram Mohan Roy formed the Brahmo Samaj which played an important role in forbidding idol worship and preaching worship of one God. He opened a temple in Calcutta, where there was no idol. While the appeal of the Brahmo Samaj remained limited to only the intellectuals and enlightened Brahmins, its impact on the culture of modern Bengal and the middle class was quite significant.
