Explanation:

The Government of India Act, 1935, was a pivotal legislation that introduced provincial autonomy. It abolished the system of 'dyarchy' (dual rule) in the provinces and granted them a significant degree of self-governance, allowing elected provincial legislatures and ministries to administer most provincial subjects without direct British interference. This was a crucial step towards greater Indian self-rule. The Government of India Act, 1858, established direct Crown rule. The Indian Council Act, 1892, introduced indirect elections. The Government of India Act, 1919, introduced 'dyarchy' but not full provincial autonomy.
