Correct answer: C. Schedule a diagnostic check with a mechanic as soon as possible.
The 'Check Engine' light indicates a problem detected by the vehicle's onboard diagnostic system. While it might not always signify an immediate breakdown, it's crucial to have it diagnosed by a mechanic to prevent potential damage, identify emissions issues, or address safety concerns.
