The Government of India Act, 1935 was a milestone in the constitutional action of India and each option provided revolves around its key features.

Option 1 suggests that the Act only provided provincial autonomy and the establishment of a Federal Court. This neglects the formation of an All India Federation at the centre, which the Act did indeed allow for.

Option 2 makes the converse error, considering the establishment of Federal Court and All India Federation as the Act`s only provisions, not mentioning provincial autonomy.

Option 3 highlights the provisions of provincial autonomy and All India Federation at the centre. It omits the establishment of a Federal Court, which was a crucial part of the Act.

Option 4 correctly states that all three aspects — provincial autonomy, the establishment of a Federal Court, and All India Federation — were part of the Government of India Act, 1935. Therefore, this is the correct option.
