The correct answer is (b) Rajya Sabha.
The Rajya Sabha is the upper house of the Indian Parliament. It is a permanent body and cannot be dissolved. However, it can be abolished by a constitutional amendment.
The Lok Sabha is the lower house of the Indian Parliament. It is a directly elected body and can be dissolved by the President on the advice of the Prime Minister.
State Legislative Assemblies are the lower houses of the state legislatures in India. They are directly elected bodies and can be dissolved by the Governor on the advice of the Chief Minister.
State Legislative Councils are the upper houses of the state legislatures in India. They are not directly elected, but are indirectly elected by members of the Legislative Assemblies and local bodies. They can be dissolved by the Governor on the advice of the Chief Minister.
The Rajya Sabha is a permanent body because it is a part of the basic structure of the Constitution. The basic structure of the Constitution cannot be amended. The Lok Sabha, State Legislative Assemblies, and State Legislative Councils are not part of the basic structure of the Constitution and can be amended.
