The correct option is C Any third party can file it.
The objective of the Public Interest Litigation (PIL) is to enable a third party to file a case, a person whose rights are not being violated, but is concerned about the public interest. In 1981, the rules of public litigation were formally laid down by the ‘Committee of Judicare’. The Committee’s report emphasised that the person presenting or filing the case need not be one whose rights are directly infringed.
