The correct answer pertains to NOTAM (D) distribution, which is specifically focused on information related to navigational facilities. NOTAM (D) is a type of Notice to Airmen that conveys essential information about significant changes or conditions affecting navigational aids, like beacons and approaches. This information is particularly crucial for pilots operating under Instrument Flight Rules (IFR), as it ensures they have the latest updates on navigation-related resources critical for safe flight.

NOTAMs can vary in their content and significance. For example, FDC NOTAMs typically cover regulatory changes and procedures rather than the specifics of navigational facilities. Graphic Notices convey information visually, but they do not specifically target navigational facilities as NOTAM (D) does. Local NOTAMs tend to pertain to specific regions or airports and may not encompass broader navigational facility changes, making NOTAM (D) the most direct source for that type of information. Therefore, when seeking updates on navigational facilities, NOTAM (D) distribution is the most appropriate and relevant source.
