Explanations:The question asks about social reformers from Bengal, a state in eastern India. Social reformers are individuals who advocate for changes in society to improve the lives of people, often focusing on issues such as education, women's rights, and religious practices. Bengal has a rich history of social reformers who have made significant contributions to Indian society and culture.
Ramakrishna Paramahamsa, born in 1836 in Hooghly district, West Bengal, was a prominent spiritual leader and mystic. He is known for his teachings on the unity of all religions and his influence on his disciple, Swami Vivekananda. Ramakrishna's spiritual practices and teachings have had a profound impact on Hinduism and have inspired many social and religious reforms in India.
Swami Vivekananda, born in 1863 in Calcutta (now Kolkata), West Bengal, was a key figure in the Indian independence movement and a prominent disciple of Ramakrishna Paramahamsa. He is best known for his speech at the Parliament of the World's Religions in Chicago in 1893, where he introduced Hinduism to the Western world. Vivekananda's teachings emphasized the importance of education, social service, and the unity of all religions. He founded the Ramakrishna Mission, which continues to work towards social and spiritual upliftment.
Dadabhai Naoroji, on the other hand, was born in 1825 in Bombay (now Mumbai), which is in the state of Maharashtra, not Bengal. He was a prominent Indian nationalist and one of the early leaders of the Indian National Congress. Naoroji is known for his contributions to Indian nationalism, education, and economic reforms. He was the first Indian to be elected to the British House of Commons and is often referred to as the "Grand Old Man of India."
Therefore, the correct answer is that only Ramakrishna Paramahamsa and Swami Vivekananda are social reformers from Bengal. This question tests the student's knowledge of the origins and contributions of significant social reformers in Indian history, particularly those associated with Bengal.
