India has not adopted proportional representation in the election of:

The correct answer is Option (4) → Local Self Government

Under proportional representation, a party or candidate gets seats in proportion to the votes received; India uses it in the form of the single transferable vote for its indirect elections:

• President — elected by the elected members of Parliament and of the state and union territory Legislative Assemblies

• Vice-President — elected by the members of both Houses of Parliament

• Rajya Sabha and Vidhan Parishad — members elected by the members of the Legislative Assemblies and, for the Vidhan Parishad, also by local bodies, graduates and teachers

Members of local self-government bodies (panchayats and municipalities), like those of the Lok Sabha and the Vidhan Sabhas, are chosen by direct election under the first-past-the-post system: the candidate with the most votes in a ward wins, so proportional representation is not used there.
