The state that has a bicameral legislature in India is Jammu and Kashmir. In the rest of the states, the legislature is unicameral, which means it has only one house.

Explanation:

A bicameral legislature consists of two houses or chambers: the upper house and the lower house. This system is usually adopted by federal countries like India to ensure a proper representation of different states or regions.

In India, the Parliament consists of two houses - the Rajya Sabha (Council of States) and the Lok Sabha (House of the People). The Rajya Sabha is the upper house, representing the states and union territories, while the Lok Sabha is the lower house, representing the people of India.

However, at the state level, most states have a unicameral legislature, which means they have only one house. The members of this house are elected by the people through direct elections. The chief minister and the council of ministers are responsible for the functioning of the state government.

But there is an exception to this rule. The state of Jammu and Kashmir has a bicameral legislature, consisting of two houses: the Legislative Assembly and the Legislative Council. The Legislative Assembly is the lower house, elected by the people, while the Legislative Council is the upper house, with members elected by various constituencies, including local bodies, graduates, and teachers.

The purpose of having a bicameral legislature is to ensure a balance of power and representation. The upper house represents the states or regions, while the lower house represents the people. This system allows for a more comprehensive and inclusive decision-making process.

In conclusion, while most states in India have a unicameral legislature, Jammu and Kashmir is the only state with a bicameral legislature, consisting of the Legislative Assembly and the Legislative Council. This system ensures a proper representation of both the people and the states or regions in the legislative process.
