How many passengers (Pax) can be loaded on the C-5 Galaxy?

The C-5 Galaxy is a large military transport aircraft designed to carry both cargo and personnel. The correct choice of 73 passengers reflects the aircraft's configuration when it is set up for personnel transport. While the C-5 can accommodate a variety of cargo types and configurations, the specified number of 73 typically refers to its capability when configured with standard seating for troop transport. This includes considerations for comfort and logistics, as it is essential for military operations to have a suitable number of personnel onboard during missions.

In contrast, the other options provide numbers that do not align with the aircraft's operating specifications for passenger transport. For example, 50 would be insufficient given the design and purpose of the C-5 for military operations, while 100 and 150 exceed the standard seating configuration typically used for real-world missions. Understanding these specifications is critical for accurate load planning and operational effectiveness within military air transport contexts.
