Explanation:

• The Morcha Chabian campaign for the recovery of the keys of the Golden Temple treasury, marked a dramatic episode in the Sikh agitations in the early 1920s, to reform the management of their places of worship. Hence, option (b) is the correct answer.
• The Golden Temple at Amritsar had been managed by a government-nominated sarbrdh (controller) since 1849. The Golden Temple came under Akali control in October 1920, but the Shiromani Gurdwara Parbandhak Committee nominated the old sarbrdh, Sundar Singh Ramgarhia, as a member of the new committee and appointed him to continue to administer the affairs of the Golden Temple. Even though the sarbrdh now functioned under the directions of the Committee, but, since he still retained possession of the keys of the Toshakhana (treasury) of the Golden Temple, some of the Akali reformers felt that Governmental control, however nominal, still remained.
• On 11 November, the Government attempted to replace Sundar Singh with their own appointee Captain Bahadur Singh, in effect overriding the choice of the SGPC. The Shiromani Gurdwara Parbandhak Committee refused to recognize the new sarbrdh. On 12 November 1921, a protest meeting was convened in Bagh Akaliari at Amritsar which was addressed by Baba Kharak Singh and other Akali leaders. Akali meetings took place at Gujrariwala, Gujjar Khan and other places. Captain Bahadur Singh resigned, but the Government remained adamant. Dan Singh of Vachhoa and Jasbal, two prominent Akalis, were arrested at a divan at Ajnala on 26 November 1921.
• Failing to control the Sikh protests and foreseeing how it might affect Sikh soldiers and the peasantry, the government announced on 3 January 1922 its decision to return the keys to the Shiromani Committee on 7/5 January 1922, but the Committee refused to accept the keys until all the Sikhs arrested during the movement were released unconditionally.
• The matter was raised in the Punjab Legislative Council on 11 January 1922, Sir John Maynard, the Home Member announced the release of all Sikhs under detention. However, the Akalis refused to go and fetch the keys from the Deputy Commissioner. A Government official was eventually sent to deliver the keys wrapped in a piece of red silk to Baba Kharak Singh, president of the Shiromani Gurdwara Parbandhak Committee, at a divan on 19 January 1922 at the Akal Takht.
• In this agitation, the Sikh reformers were also joined by the Congress volunteers in Punjab. Since Mahatma Gandhi's non-cooperation movement was already going on, the Punjab Government thought of isolating the Akali reformers from the congress program of non-cooperation by releasing all the Akali volunteers arrested in connection with the A agitation over the keys affair and returning the keys of the Golden temple treasury to the President of the committee. This victory of the Akali reformers was seen by the national leaders as a victory of the forces of nationalism.
