Which one of the following is part of the electoral college for the election of the President of India but does not form part of the forum for his impeachment?

The President of India is elected by an electoral college consisting of the elected members of both Houses of Parliament and the elected members of the State Legislative Assemblies. However, the impeachment process of the President is a quasi-judicial procedure conducted only in Parliament. It involves only the members of the Lok Sabha and the Rajya Sabha. Even though the elected members of the State Legislative Assemblies participate in the election of the President, they have no role in the impeachment process. State Legislative Councils are excluded from both the election and the impeachment process. Therefore, State Legislative Assemblies fit the specific criteria of participating in the election but not in the impeachment.
