Provincial autonomy was introduced in India through the Government of India Act, 1935. This act granted greater powers to the provinces of British India and allowed for the establishment of a federal structure. It replaced the previous Government of India Act, 1919. The act divided British India into numerous provinces, giving them considerable legislative and executive autonomy. The provinces had the power to make and enforce laws within their jurisdiction, levy and collect taxes, and manage their own finances. The act also introduced the concept of dyarchy, where certain subjects were assigned to the control of the Governor and others to the provincial government. It is important to note that none of the individuals listed in the options played a direct role in introducing provincial autonomy through the Government of India Act, 1935.
