Which of the following decisions cannot be taken by the President of India?

a. To attack an enemy state b. To dismiss the Chief Justice c. To appoint a speaker of his choice d. To ask for consideration a bill passed by both houses

This is correct as the President cannot do a, b and c. Though the President is the Supreme Commander of the Armed Forces, but he cannot order attack on an enemy state as the Parliament will take a decision on this and the President can do so only on the advice of the Parliament. The President cannot dismiss the Chief Justice as the CJI can be removed only through a process of impeachment by the Parliament. Minister of Parliamentary Affairs selects a protem speaker. The appointment has to be approved by the President.
