The applicability of the FIA Act extends to:

The correct answer is None of these because the choices provided do not accurately capture the precise statutory application parameters established by the law.

• None of these: This is the correct choice. According to Section 1(2) of the Act, the law extends to the whole of Pakistan and applies strictly to all citizens of Pakistan and public servants, wherever they may be. Under Section 2(e), this explicitly includes employees of corporations set up, controlled, or administered by the Federal Government. Because option 1 is too broad (all corporations), option 2 is narrow, and option 3 incorrectly adds provincial spheres, 'None of these' remains the accurate answer key.
• Incorrect Options:
  • Employees of all corporations: This is incorrect. The Act does not extend to purely private or provincial corporate bodies.
  • Employees of Federal & Provincial Governments: This is incorrect. Provincial government structures are explicitly outside the primary investigative scope of the FIA unless special scheduling or joint team scenarios apply.
