Which type of route requires more time and fuel due to greater distance, but is easier to navigate?

The choice of a Rhumb Line is correct because it represents a path on the Earth's surface that maintains a constant compass direction. This characteristic makes it relatively easier for navigators to follow since they do not need to change their heading throughout the journey. Despite requiring more time and fuel due to covering a longer distance compared to a straight great circle route, the simplicity of navigation makes it appealing for certain types of travel, especially over longer distances where constant directional changes might complicate the navigation.

Great Circle Routes are the shortest distance between two points on the sphere of the Earth, leading to less travel time and fuel consumption, although they can be more complex to navigate since they involve changing headings. The Direct Line implies a straight path between two points, which does not exist on the Earth’s surface if considering its curvature, also making it less relevant in the context of establishing routes. A Circular Path, while perhaps easier in some navigation contexts, generally does not apply to routing in the same way that Rhumb Lines do, and often suggests a less efficient trajectory in terms of distance and resource utilization.
