According to the Constitution of India, if the President so requires, it shall be the duty of the Prime Minister to submit for the consideration of the Council of Ministers any matter on which a decision has been taken by a Minister, but which has not been considered by the Council. This ensures:

• A.  Collective responsibility
• B.  The status of the Prime Minister as the first among the equals
• C.  The power of the President to nullify the decision of the Minister
• D.  The inherent power of the Minister to take a decision independent of the Council of Ministers
