Explanation:

• Option (c) is correct:
• Dr. B.R. Ambedkar proudly acclaimed that the Constitution of India has been framed after ‘ransacking all the known Constitutions of the World’. The structural part of the Constitution is, to a large extent, derived from the Government of India Act of 1935. The philosophical part of the Constitution (the Fundamental Rights and the Directive Principles of State Policy) derive their inspiration from the American and Irish Constitutions, respectively.
• The most profound influence and material source of the Constitution is the Government of India Act, 1935. The Federal Scheme, Judiciary, Governors, Emergency Powers, the Public Service Commissions, and most of the administrative details are drawn from this Act. The critics said that the framers of the Constitution have included a large number of the provisions of the Government of India Act of 1935 into the Constitution of India.
• Hence, they called the Constitution as a “Carbon Copy of the 1935 Act”.
