The Vice President of India is elected by the members of an electoral college…

Article 66(1) of the Constitution provides that the Vice-President of India is elected by an electoral college consisting of the members of both Houses of Parliament, voting by the system of proportional representation through the single transferable vote, by secret ballot.

This differs from Article 54, which builds the President's electoral college only from elected members of both Houses of Parliament together with elected members of the State and Union Territory Legislative Assemblies; Article 66 carries no such “elected members only” restriction, and it does not draw on the State Legislatures at all.

1. Identify the governing provision: Article 66(1) of the Constitution prescribes the electoral college for electing the Vice-President.

2. Read its wording precisely — it names ‘the members of both Houses of Parliament’, with no qualifier limiting this to elected members.

3. Apply this to the composition: the electoral college spans both the Lok Sabha and the Rajya Sabha, and it includes any nominated members of the Rajya Sabha along with the elected members.

4. Match this composition to the options offered: it corresponds to ‘all the members of both the Houses of the Parliament.’

• Article 54 (the President's electoral college) is explicitly restricted to elected members of Parliament plus elected members of the State/UT Legislative Assemblies — nominated members are excluded there.

• Article 66 (the Vice-President's electoral college) has no such “elected only” restriction and includes no State Legislature representation at all — it draws solely and fully from both Houses of Parliament.

• This textual contrast between the two Articles is corroborated by the Election Commission's official description of the Vice-Presidential electoral college, which lists elected Rajya Sabha members, nominated Rajya Sabha members, and elected Lok Sabha members as included.

Therefore, the Vice-President of India is elected by an electoral college consisting of all the members of both the Houses of the Parliament.
