The correct choice is related to the concept of crossing courses in aviation. When two courses have an angular difference of between 45 and 135 degrees, it indicates that they are not parallel but rather intersect at an angle that allows for a potential crossing of paths. This angular difference denotes that the courses will meet at some point, which is significant for air traffic control and ensuring safe separation between aircraft.

Crossing courses are vital for controllers to understand because they must manage the traffic to ensure that aircraft do not collide as they approach the intersection. The specific angle range indicates a significant enough divergence from being opposite or parallel, which would necessitate different management strategies.

In contrast to crossing courses, same courses indicate paths that run parallel and do not intersect; opposite courses would be those that run directly opposite each other, typically a 180-degree separation, and diverging courses are those that run away from each other. Hence, recognizing crossing courses with an angular difference ranging from 45 to 135 degrees is crucial in the context of air traffic control and navigational safety.
