Let's review the official regarding their colour-coded international alert system:
• This is a specialized financial intelligence tool. It is issued specifically to alert member states to identify, monitor, and trace illicit criminal assets (like laundered money or stolen antiquities) across borders.
• Unlike a Red Notice (which demands arrest), a Blue Notice is an inquiry. It is issued to collect additional intelligence regarding a person's identity, location, or activities related to an ongoing investigation.
• This serves a morbid but crucial forensic and humanitarian purpose. It is circulated globally to seek information to establish the identity of deceased, unidentified bodies.
• This is a preventative alert. It is issued to warn other countries about an individual’s known criminal activities if they are considered a possible threat to public safety (e.g., a known serial offender traveling abroad).
A-4, B-2, C-1, D-3. Option C is the correct answer.
