After the death of Raja Rammohan Roy, the Brahmo Samaj split into two sections; the Brahmo Samaj of India and the Adi Brahmo Samaj. Who were the leaders of the two sections respectively ?

Following the death of Raja Rammohan Roy, the Brahmo Samaj was revitalized by Debendranath Tagore, who joined in 1843 [4]. In 1858, Keshab Chandra Sen joined the movement and was appointed 'acharya' by Tagore [1][t1]. However, ideological rifts emerged as Sen advocated for more radical social reforms, such as inter-caste marriages and the inclusion of teachings from all religions, which Tagore found too cosmopolitan [1][t1]. This friction led to a formal split in 1866. Keshab Chandra Sen and his progressive followers founded the 'Brahmo Samaj of India' (also known as Bharatvarshiya Brahmo Samaj), while the original section under Debendranath Tagore's leadership became known as the 'Adi Brahmo Samaj' [2][t1][t2]. Radhakanta Deb, mentioned in other options, was actually an opponent of the Samaj who led the orthodox Dharma Sabha [t3][t4].
