The correct choice is "Modern Airliner" because the Boeing 747 and McDonnell-Douglas DC-10 are both large, jet-powered aircraft designed primarily for commercial passenger transport and long-haul travel. They represent a significant evolution in aviation technology and are characterized by features such as high-capacity seating, advanced aerodynamics, and increased fuel efficiency compared to earlier aircraft designs.

These aircraft are widely recognized for their role in the development of the airline industry's capability to service international routes and their contribution to the accessibility of air travel for the public. As modern airliners, they are designed to meet the demands of contemporary air travel, providing essential services to major air carriers that operate extensive networks around the globe.

The other options pertain to different categories or functions of aircraft. For instance, regional airliners generally refer to smaller planes tailored for shorter distances and less passenger capacity. Charter services are typically non-scheduled flights operated with smaller aircraft for specific groups or purposes. Freighter aircraft are designed specifically for cargo transport rather than passenger travel. Therefore, the designation of Boeing 747 and DC-10 as modern airliners captures their intended use and technological advancements accurately.
