The correct answer is A. 12.
The Legislative Council is the upper house of the bicameral legislature of the Indian states. The number of members in the Legislative Council is determined by the Constitution of India, which states that the total number of members in the Council shall not exceed one-third of the total number of members in the Legislative Assembly. The Governor of the state nominates 12 members to the Legislative Council. The remaining members are elected by members of local bodies, graduates, teachers, and registered medical practitioners.
Option B is incorrect because it is the number of members that are elected by members of local bodies. Option C is incorrect because it is the fraction of the total strength of the house that is elected by graduates, teachers, and registered medical practitioners. Option D is incorrect because it is the fraction of the total strength of the house that is nominated by the Governor.
