The Morley-Minto Reforms were introduced in the year 1909. These reforms were implemented in British India and aimed at granting limited legislative powers to Indians. The reforms were named after John Morley, who was the Secretary of State for India, and Lord Minto, who was the Viceroy of India at that time.

Option 1, 1909, is the correct answer as it correctly identifies the year in which the Morley-Minto Reforms were introduced. Option 2, 1919, is incorrect as it refers to the introduction of the Montagu-Chelmsford Reforms. Option 3, 1924, and option 4, 1935, do not relate to the Morley-Minto Reforms and are therefore incorrect.
