Explanation:

• In 1829 Raja Rammohun Roy founded a new religious society, the Brahma Sabha, later known as the Brahmo Samaj, whose purpose was to purify Hinduism and to preach theism or the worship of one God. The new society was to be based on the twin pillars of reason and the Vedas and Upanishads. It was also to incorporate the teachings of other religions.
• The Brahmo tradition of Raja Rammohun Roy was carried forward after 1843 by Devendranath Tagore, who also repudiated the doctrine that the Vedic scriptures were infallible, and after 1866 by Keshub Chandra Sen. The Brahmo Samaj made an effort to reform Hindu religion by removing abuses, by basing it on the worship of one God and on the teachings of the Vedas and Upanishads, and by incorporating the best aspects of modern western thought.
• Most of all it based itself on human reason which was to be the ultimate criterion for deciding what was worthwhile and what was useless in the past or present religious principles and practices. For that reason, the Brahmo Samaj denied the need for a priestly class for interpreting religious writings. Every individual had the right and the capacity to decide with the help of his own intellect what was right and what was wrong in a religious book or principle.
• The Brahmos were also great social reformers. They actively opposed the Caste system and childmarriage and supported the general uplift of women, including widow remarriage, and the spread of modem education to men and women.
• Hence, all the given statements are correct.
