The correct answer is: a) Control of Gurdwaras.
The Akali Movement was a Sikh agitation for control of Gurdwaras, which are Sikh temples. The movement began in the early 1920s and lasted for several years. The Akalis were successful in their demands, and the Gurdwaras were eventually placed under the control of the Shiromani Gurdwara Parbandhak Committee (SGPC), a body elected by Sikhs.
The Akali Movement was a significant event in Sikh history. It helped to strengthen the Sikh community and to assert its identity. The movement also played a role in the independence of India.
The other options are incorrect. Option b) is incorrect because the Akali Movement was not agitating for an independent Sikh homeland. Option c) is incorrect because the Akali Movement was not agitating for the abolition of the caste system. Option d) is incorrect because the Akali Movement was not agitating for land reforms.
