Explanation:

Statement 1 is correct. Mahatma Gandhi was awarded the Kaisar-i-Hind in 1915 by The Lord Hardinge of Penshurst for his contribution to ambulance services in South Africa during the Boer War. In protest of the Jallianwala Bagh Massacre, Rabindranath Tagore renounced his knighthood in protest and Mahatma Gandhi gave up the title of Kaiser-i-Hind.

Statement 2 is incorrect. After the Jallianwala Bagh Massacre, on October 14, 1919, the Government of India announced the formation of the Disorders Inquiry Committee,also known as the Hunter Committee/Commission after the name of chairman, Lord William Hunter, former Solicitor-General for Scotland and Senator of the College of Justice in Scotland. The purpose of the commission was to “investigate the recent disturbances in Bombay, Delhi and Punjab, about their causes, and the measures taken to cope with them.''
There were three Indians among the members, namely, Sir Chimanlal Harilal Setalvad, Vice-Chancellor of Bombay University and advocate of the Bombay High Court; Pandit Jagat Narayan, lawyer and Member of the Legislative Council of the United Provinces; and Sardar Sahibzada Sultan Ahmad Khan, lawyer from Gwalior State.

Statement 3 is correct: The clergy of the Golden Temple, led by Arur Singh, honoured Dyer by declaring him a Sikh.The honouring of Dyer by the priests of Sri Darbar Sahib, Amritsar, was one of the reasons behind the intensification of the demand for reforming management of Sikh shrines already being voiced by societies such as the Khalsa Diwan Majha and Central Majha Khalsa Diwan. This resulted in the launch of what came to be known as the Gurdwara Reform movement.
