The correct option is A 1911
In the year 1911 Calcutta became the former capital of British India and it was shifted to Delhi. The decision was taken during the reign of Lord Hardinge, the then Viceroy of India. Hardinge's explanation was that Calcutta was located in the extreme east so the capital should be centralized for betterment. Though historians stated that in Bengal the situation was gradually going beyond control and rigorous extremist movement was giving sleepless nights to the British Raj.
