Which of the following is not an intelligence agency?

The correct answer is Interpol. Interpol (the International Criminal Police Organization) is an international police cooperation organization that facilitates cross‑border police collaboration between its 196 member countries. It is not a national intelligence agency. The other options are all well‑known intelligence agencies:

• Mossad: The national intelligence agency of Israel.
• RAW: The Research and Analysis Wing, the external intelligence agency of India.
• MI6: The Secret Intelligence Service, the foreign intelligence agency of the United Kingdom.

Therefore, the organization that is not an intelligence agency is "Interpol".
