A pilot cleared for an instrument approach must complete the approach unless

• A. Receives approval for a contact approach
• B. Is cleared for the visual approach
• C. Cancels IFR
• D. The weather becomes VFR

Answer: (C)

The key idea is that when you’re cleared for an instrument approach you’re operating under IFR and are expected to complete that approach unless you explicitly cancel IFR. Canceling IFR ends the instrument-flight Rules obligations, letting you switch to VFR and land visually if weather and visibility permit, or follow a different clearance. This is why the correct choice is the one that states you can avoid finishing the instrument approach only by canceling IFR. Receiving a different clearance, like a contact approach, or the weather turning VFR, does not automatically relieve you from completing the instrument approach; you’d need to cancel IFR first to operate strictly under VFR.
