The term public servant denotes:

The correct answer is Section 21 of Pakistan Penal Code because this specific statutory section provides the foundational legal definition of who qualifies as a public servant under Pakistani law.

• Section 21 of Pakistan Penal Code: This is the correct choice. Section 2(e) of the FIA Act, 1974, explicitly borrows its baseline definition of a public servant from Section 21 of the Pakistan Penal Code (PPC) 1860, which details eleven distinct categories of public officers, including military officers, judges, court officials, and individuals employed by federally controlled organizations.
• Incorrect Options:
  • Section 19 of Pakistan Penal Code: This is incorrect. Section 19 of the PPC defines the word 'Judge' rather than a public servant.
  • Section 20 of Pakistan Penal Code: This is incorrect. Section 20 of the PPC provides the statutory definition for a 'Court of Justice'.
