Correct option is D
The correct answer is option (d) Sati system.
Explanation
Raja Ram Mohan Roy was a prominent social reformer in India who fought against many social evils, but he is most famous for his efforts to abolish the Sati system. Sati was the practice where a widow was forced or chose to self-immolate on her husband's funeral pyre. Raja Ram Mohan Roy strongly opposed this practice, considering it inhumane and a violation of human rights.
In 1829, after significant advocacy by Roy and his followers, the British East India Company passed the Regulation XVII, which prohibited the practice of Sati in India, marking a significant step in social reform.
