The correct answer is: A. Article-166
Article 166 of the Indian Constitution deals with the appointment of the Chief Minister and other Ministers. It states that the Governor of a State shall appoint as Chief Minister the person who is most likely to command the confidence of the majority of the members of the Legislative Assembly. The Governor shall also appoint other Ministers on the advice of the Chief Minister.
The Chief Minister is the head of the State Government and is responsible for the administration of the State. He/She is assisted by the other Ministers who are collectively known as the Council of Ministers. The Chief Minister has the power to allocate portfolios to the Ministers and to remove them from office. He/She is also the leader of the Legislative Assembly and is responsible for the smooth functioning of the Assembly.
The Chief Minister is a very important position in the Indian political system. He/She is the head of the State Government and is responsible for the administration of the State. The Chief Minister is also the leader of the Legislative Assembly and is responsible for the smooth functioning of the Assembly.
