The number of members in the Karnataka Legislative Council cannot exceed:

1/4th of the Assembly
1/3rd of the Assembly
1/2 of the Assembly
2/3rd of the Assembly

The correct answer is: A) 1/4th of the Assembly

The Karnataka Legislative Council is the upper house of the Karnataka Legislature, the state legislature of the Indian state of Karnataka. The council has 75 members, who are elected by an electoral college consisting of members of the Legislative Assembly, members of the Legislative Council, and local self-government representatives. The term of office of a member of the Legislative Council is six years.

The number of members in the Legislative Council cannot exceed one-fourth of the total number of members in the Legislative Assembly. This is because the Legislative Council is a permanent body, while the Legislative Assembly is a temporary body that is dissolved after every five years. The Legislative Council is meant to provide a check on the power of the Legislative Assembly and to represent the interests of the minority groups in the state.

The other options are incorrect because they are not in accordance with the provisions of the Karnataka Legislative Council Act, 1952.
