Consider the following:1.Calcutta Unitarian Committee2.Tabernacle of New Dispensation3.Indian Reform AssociationKeshab Chandra Sen is associated with the establishment of which of the above?

1. A

   1 and 3 only

   The Calcutta Unitarian Committee (1823) is associated with Rammohan Roy, Dwarkanath Tagore and William Adam, not with Keshab Chandra Sen. Pairing it with the Indian Reform Association therefore fails. 1 and 3 only is not the key.

2. B

   2 and 3 only

   Keshab Chandra Sen established the Tabernacle of New Dispensation (Naba Bidhan, 1868) after his break within the Brahmo movement, and he founded the Indian Reform Association in 1870 for social and moral reform. He is not the founder of the Calcutta Unitarian Committee. Statements 2 and 3 only are correct, so (b) is the official key.

3. C

   3 only

   The Indian Reform Association alone would omit the Tabernacle of New Dispensation, which Sen did establish. 3 only is incomplete.

4. D

   1, 2 and 3

   All three would credit Sen with the Calcutta Unitarian Committee. That body belongs to an earlier generation around Rammohan Roy. This option is wrong.

Summary. Official key is (b) 2 and 3 only. Keshab Chandra Sen led the Brahmo Samaj of India after 1866, proclaimed the New Dispensation, and ran the Indian Reform Association (education, temperance, charity). The Calcutta Unitarian Committee is an 1820s Rammohan–Unitarian episode. Matching questions on reform associations often mix generations; here only 2 and 3 are Sen’s. Statement 1 is the trap.
