Correct Answer: (a) Calcutta Session, 1917
Solution:Annie Besant was a British social reformer and activist whose work left an indelible mark on Indian history. Renowned for her leadership in the Theosophical Society, Besant played a pivotal role in the revival of theosophy. Her efforts in education played a significant role in establishing many educational institutions in India, including those focused on women's education. Annie Besant's engagement with the Theosophical Society began in 1889 when she joined the organization, which sought to explore spiritual philosophies and promote universal brotherhood. The Society was founded by Helena Petrovna Blavatsky and Henry Steel Olcott, and Besant quickly emerged as a leading figure. She represented the Theosophical Society at the Chicago World Parliament of Religions in 1893. Annie Besant became the second International President of the Theosophical Society in 1907 following the death of Col. H. S. Olcott. She kept this position until she died in 1933. In 1917, Annie Besant was elected the President of the Indian National Congress (INC) Calcutta session, becoming the first woman to hold this position. Her presidency marked a pivotal moment in the struggle for Indian independence, as she used her platform to advocate for constitutional reforms and greater political rights for Indians. Her campaign and the pressure of public opinion contributed to the enactment of the Montagu-Chelmsford proposals by the British Parliament.
