The answer B, DUATS (Direct User Access Terminal Service), is correct as it provides pilots with access to a variety of inflight weather information, including current weather conditions, forecasts, and advisories relevant to flight operations. This service allows users to obtain critical data while en route, which can help in making informed decisions regarding flight safety and route adjustments.

DUATS specifically caters to flight planning and can be accessed via computer systems and mobile devices, which enhances convenience for pilots seeking timely weather updates during their flights.

While TIBS (Telephone Information Briefing Service) offers weather information, it is primarily accessed via telephone and does not provide real-time inflight updates in the same way that DUATS does. ATIS (Automatic Terminal Information Service) delivers continuous broadcast of recorded aeronautical information at airports but is typically not available during flight for broader weather updates in the same depth as DUATS. AWOS (Automated Weather Observing System) provides local weather observations at airports, but like ATIS, it is more focused on specific airport conditions rather than broader inflight weather data needed on a flight path.
