The correct answer is Option C (Akali Movement).

Key Points:
• The Akali Movement (also known as the Gurdwara Reform Movement) was launched in the early 1920s by Sikh reformers.
• Its primary objective was to liberate historical Sikh Gurdwaras from the control of corrupt, hereditary priests called 'Mahants', who were backed by the British administration.
• The movement adopted non-violent Satyagraha and peaceful resistance to reclaim sacred shrines such as Nankana Sahib, Tarn Taran, and the Golden Temple in Amritsar.
• In December 1920, the Shiromani Gurdwara Parbandhak Committee (SGPC) and the Shiromani Akali Dal were established to administer Gurdwara affairs.
• The agitation culminated successfully with the enactment of the historic Sikh Gurdwaras Act of 1925, placing all Sikh shrines under the democratic governance of the SGPC.
• Key Takeaway: The Akali Movement was launched in the 1920s to liberate Sikh Gurdwaras from corrupt Mahants, leading to the Sikh Gurdwaras Act of 1925.
