The correct answer is Option (3) → Lord Irwin

The Simon Commission (the Indian Statutory Commission), headed by Sir John Simon, was appointed by the British government in November 1927 to review the working of the Government of India Act, 1919. It reached India in February 1928 and was met with black flags and the slogan ‘Simon, go back’, because it had no Indian member.

All this happened while Lord Irwin was the Viceroy of India (1926–1931).
