Explanation: Social reformers from Bengal played a pivotal role in the Indian Renaissance, a period of significant social and cultural transformation in the late 19th and early 20th centuries. This movement aimed to address various social ills and promote modernization and reform in Indian society.
Ramakrishna Paramahamsa, born in 1836 in Kamarpukur, West Bengal, was a key figure in the Bengal Renaissance. He was a mystic and yogi who emphasized the importance of devotion and the unity of all religions. His teachings had a profound impact on his disciple, Swami Vivekananda, who became a prominent figure in the spread of Indian spiritual thought to the West.
Swami Vivekananda, born in 1863 in Calcutta (now Kolkata), was a key proponent of the Vedanta philosophy and a significant figure in the introduction of Indian spiritual thought to the Western world. He is best known for his speech at the Parliament of the World's Religions in Chicago in 1893, where he introduced Hinduism to a global audience. His work in establishing the Ramakrishna Mission and the Vedanta Society furthered the spread of his teachings.
Dadabhai Naoroji, on the other hand, was born in 1825 in Bombay (now Mumbai) and was a prominent social reformer, political leader, and one of the early leaders of the Indian National Congress. He is known for his contributions to Indian nationalism and his role in advocating for Indian rights and self-governance. While Naoroji was a significant figure in the Indian independence movement, he was not from Bengal.
Therefore, the correct answer is (D) Only (A) & (B), as Ramakrishna Paramahamsa and Swami Vivekananda are both from Bengal, while Dadabhai Naoroji is from Gujarat. Understanding the geographical origins and contributions of these social reformers is crucial for comprehending the social and cultural movements of the time.
