Explanation:

The Governor of state has more discretionary powers than the President of India. He is not bound to act on the advise of the council of Ministers in certain circumstances, even he need not seek its advise. The Governors of states can act at their constitutional discretion in the following instances: When they have to reserve the bill for the consideration of the President of India, Governors can decide on their own without the advice of the Council of Ministers.The Governors of states can act at their situational discretion in the following instances: When he has to appoint a Chief Minister after no party has a clear majority in the election or when the incumbent dies in the office. Hence option 4th is correct.
