What does "Squawk Ident" instruct a pilot to do?

Answer: C — Activate their transponder for identification purposes

The instruction to "Squawk Ident" is specifically given to pilots to prompt them to activate their transponder's identification feature. When a pilot receives this command, they are expected to press the "Ident" button on their aircraft's transponder. This action sends a unique signal back to air traffic control, which helps in identifying and tracking the aircraft more easily among other targets on radar. This instruction is commonly used when air traffic controllers need to clarify the identity of a specific aircraft or to gain a more precise understanding of its location and intentions. The transponder provides a critical layer of situational awareness, ensuring safe and efficient air traffic management.
