For election to the LokSabha, a nomination paper can be filed by

The correct answer is C. Under Article 84(b) of the Constitution, a person must be an elector for a parliamentary constituency to be chosen as an MP. Section 33 of the Representation of the People Act, 1951 makes this operational: a candidate must be enrolled as an elector somewhere in India, and the nomination must be filed by such a person. Nationality and enrolment are the two conditions that matter, not residence in the particular constituency.

Why the others fail:

• A is wrong because citizenship is essential (Article 84(a)). A foreign resident cannot contest.
• B is wrong because a candidate may contest from any constituency where they are an elector, not only where they live. Residence was a requirement for Assembly elections in some earlier arrangements, but not for Lok Sabha nomination under the 1951 Act.
• D is wrong because being a citizen is necessary but not sufficient. Without being an elector, the nomination is not valid.

Core concept: the difference between eligibility to be a member (Article 84) and eligibility to be a candidate (RP Act, 1951). For Mains, this links to electoral reforms and the debate on whether a candidate should be tied to a constituency by residence.

Trap: aspirants pick B because it sounds logical. Remember the law asks for enrolment in the electoral roll, not residence in the constituency.
