Detailed Explanation:

Answer: Option 3 — Constitutional Right

The right to vote and to be elected in India is a constitutional right derived from Article 326 of the Indian Constitution, which provides for universal adult suffrage for elections to the Lok Sabha and State Legislative Assemblies. Unlike fundamental rights which are justiciable and enforceable through courts under Article 32, the right to vote is a statutory right created by the Constitution and regulated by the Representation of the People Act. The Constitution (Sixty-first Amendment) Act, 1988, lowered the voting age from 21 to 18 years to enhance democratic participation, though this right remains subject to reasonable restrictions such as non-residence, unsoundness of mind, crime, or corrupt practices.
