• D. Collaborative safety effortt by G-20 countries

Answer: (A)

ADREP is ICAO’s databank of worldwide accident and incident information for large commercial aircraft. It collects standardized reports from states about aviation accidents and serious incidents, storing them so safety analysts can identify trends, assess safety performance, and support global safety improvements. It’s not a system for gathering sensitive GPS data, not a collection of safety system inventories, and not a collaborative safety effort by the G-20—it's specifically a centralized data repository used for global safety analysis.
