On 24th January 1868, Keshub laid the foundation stone of his new church, the Brahmo Samaj of India Tabernacle of New Dispensation, and the newly constructed chapel was consecrated on 22nd August 1869. Keshab Chandra Sen was also associated with the Indian Reform Association. Statements 2 and 3 are correct.
