Explanation:

Henry Louis Vivian Derozio, a teacher at Hindu College, Calcutta, in the 1820s, promoted radical ideas and encouraged his pupils to question all authority. Referred to as the Young Bengal Movement, his students attacked tradition and custom, demanded education for women and
campaigned for the freedom of thought and expression
Pair 1 is correct: The Derozians carried forward Rammohan Roy’s tradition of public education on social, economic and political questions. For instance, they demanded induction of Indians in higher grades of services, protection of ryots from oppressive zamindars, better treatment to Indian labour abroad in British colonies, revision of the Company’s charter, freedom of press and trial by jury.
Pair 2 is incorrect: The Derozians failed to have a long-term impact. Derozio was removed from the Hindu College in 1831 because of his radicalism. It gained limited success due to the prevailing social conditions at that time. Time was not ripe for the adoption of radical ideas. Further, there was no support from any other social group or class. The Derozians lacked any real link with the masses.
Pair 3 is correct: Many of Derozio's students found logic and substance in the arguments of the Christian missionaries against many superstitious and cruel beliefs of the Hindus. Quite a number of them including Dakhinaranjan Mukhopadhyay and Krishnamohan Bandyopadhyay even left Hinduism and embraced Christianity.
