The correct answer is "1 and 3 only" because these powers of the Governor are discretionary and not subject to the advice of the council of ministers. The Governor can recommend to the President the imposition of President's Rule (Option 1) if the constitutional machinery in the state breaks down. Similarly, reserving certain bills for presidential consideration (Option 3) is also a discretionary power, as it is based on the Governor's judgment regarding the bill's implications on central-state relations. In contrast, appointing ministers (Option 2) and making rules to conduct state business (Option 4) are generally exercised on the advice of the council of ministers and do not fall under the category of discretionary powers.
