"ब्राम्होसमाज" स्थापन करण्यापूर्वी राजा राममोहन रॉय यांनी इ.स. 1815 साली 'आत्मीय सभा' स्थापन केली, त्यावेळी त्यांच्या बरोबर खालील कोणते सहकारी होते ?
(a) द्वारकानाथ टागोर, प्रसन्नकुमार टागोर
(b) डॉ. राजेंद्रलाल मिश्र, राजा कली
(c) शंकर घोषाल, आनंद प्रसाद बॅनर्जी
(d) केशवचंद्र सेन, देवेंद्रनाथ टागोर

The correct answer is Option C ((a), (b) and (c) only).

Key Points:
• In 1815, Raja Ram Mohan Roy founded the Atmiya Sabha (Society of Friends) in Calcutta to propagate monotheism and campaign against idol worship and social dogmas.
• Early Associates (1815):
• Dwarkanath Tagore and Prasannakumar Tagore (leading progressive zamindars and philanthropists).
• Dr. Rajendralal Mishra and Raja Kali Shankar Ghoshal.
• Anand Prasad Banerjee (Zamindar of Telinipara), Baidyanath Mukhopadhyay, Brojomohun Mojumdar.
• Chronological Clarification:
• Debendranath Tagore joined the Brahmo Samaj later in 1842 (Tattvabodhini Sabha merger), and Keshub Chandra Sen joined in 1857. Thus, statement (d) is incorrect for the 1815 founding era.
• Atmiya Sabha laid the institutional foundation that evolved into the Brahmo Sabha in August 1828.
• Key Takeaway: Atmiya Sabha (1815) founders/allies included Dwarkanath Tagore, Prasannakumar Tagore, Dr. Rajendralal Mishra, and Anand Prasad Banerjee (not Keshub Sen/Debendranath Tagore).
