भ्रष्टाचार प्रतिबंध अधिनियम, 1988 मधील कलम 17 नुसार गटात न बसणारा पर्याय शोधा.

The correct answer is Option D (Superintendent of Police).

Key Points:
• Authorized Investigating Officers under Section 17 of PCA, 1988:
• Ranks Permitted to Investigate: Section 17 explicitly specifies that no police officer below the following ranks shall investigate any offence punishable under this Act without an order of a Metropolitan Magistrate or a Magistrate of the first class:
• (a) In Delhi: An Inspector of Police (Option 1);
• (b) In presidency towns (Mumbai, Kolkata, Chennai): An Assistant Commissioner of Police (ACP) (Option 2);
• (c) Elsewhere: A Deputy Superintendent of Police (DySP) (Option 3).
• The Odd Man Out: Superintendent of Police (SP) is a higher supervisory rank, not listed as the minimum statutory threshold officer designated under Section 17 clauses (a), (b), or (c).
• Hence, Option (4) [Superintendent of Police] is the odd one out.
• Key Takeaway: Section 17 designates Inspectors (Delhi), ACPs (Presidency towns), and DySPs (Elsewhere) as primary investigators; SP is the odd rank.
