PIO stands for which of the following?

• A. Preliminary Inquiry Officer
• B. Primary Investigation Officer
• C. Preliminary Internal Officer
• D. Public Inquiry Officer

Answer: (A)

PIO in this context refers to the person handling the early, pre-investigation steps of an inquiry. The term Preliminary Inquiry Officer fits the sequence of actions: it’s about establishing whether there is enough basis to proceed, gathering basic facts, and flagging leads before a full investigation. This makes it the best match for the acronym in this exam setting, where PIO is about an initial examination rather than public communications. The other possibilities denote different roles or domains—Public Information Officer is a common usage in other settings, while Primary Investigation Officer or Preliminary Internal Officer don’t align with the described role or standard terminology in this context.
