The correct answer is (c), Article 212.
Article 212 of the Indian Constitution empowers the Governor to issue an ordinance when the State Legislature is not in session. An ordinance is a law that is passed by the Governor on the advice of the Council of Ministers. It has the same effect as a law passed by the State Legislature.
Article 210 deals with the duration of the sessions of the State Legislature. Article 211 deals with the prorogation of the State Legislature. Article 213 deals with the dissolution of the State Legislature.
