In the ICAO Threat and Error Management (TEM) model applied to air traffic control, what is the recommended response when a controller detects that an issued clearance contained an error?

1. Promptly correct the clearance, protect separation, and follow the applicable occurrence-reporting procedure
2. Continue with the original clearance to avoid confusion and address it after the shift ends
3. Transfer the affected aircraft to another controller to resolve the error
4. Wait until the pilot queries the clearance before acknowledging the error
