Correct Option (c):
Article 75(1) of the Constitution stipulates that the Prime Minister shall be appointed by the President, and the other Ministers shall be appointed by the President on the advice of the Prime Minister. This constitutional provision grants the Prime Minister complete discretion in selecting individuals to serve as ministers in the Council of Ministers. While the formal appointment is made by the President, it is solely based on the Prime Minister's recommendation. A person appointed as a minister is not required to be a member of Parliament at the time of appointment, but must become a member of either House within six months, as per Article 75(5).
Incorrect Options:
Option (a) is incorrect. The Prime Minister is not restricted to choosing ministers only from among members of Parliament. As per Article 75(5), a person who is not a member of either House of Parliament can be appointed as a minister, but must become a member of either House within six months from the date of appointment.
Option (b) is incorrect. The Prime Minister exercises full discretion in the choice of ministers. The Constitution does not mandate consultation with the President of India for the selection of cabinet members; the President acts on the Prime Minister's advice in this matter.
Option (d) is incorrect. The President of India does not possess discretionary powers regarding the choice of ministers. The appointment of ministers, other than the Prime Minister, is made by the President strictly on the advice of the Prime Minister, as stipulated by Article 75(1). This confirms the Prime Minister's extensive power in forming the Council of Ministers.
