The correct answer is: a) Promote Sikh identity and education.
The Singh Sabha Movement was a social and religious reform movement that began in the Punjab region of India in the late 19th century. The movement aimed to revive and reform Sikhism, and to promote Sikh identity and education. The Singh Sabha Movement was successful in restoring many aspects of Sikh tradition, and in raising the status of Sikhs in Indian society.
Option b) is incorrect because the Singh Sabha Movement did not aim to establish an independent Sikh state. The movement was focused on religious and social reform, not on political independence.
Option c) is incorrect because the Singh Sabha Movement did not support British rule in India. The movement was critical of British rule, and it called for greater self-government for Indians.
Option d) is incorrect because the Singh Sabha Movement did not advocate for social reforms within Hinduism. The movement was focused on Sikhism, not on Hinduism.
