Answer Details
The shortest flying route between any two points on the earth's surface lies along a Great Circle. A Great Circle is the largest circle that can be drawn around the surface of a sphere, such as the Earth. It is formed by the intersection of a plane that passes through the center of the sphere and divides it into two equal halves.
When we want to fly between two points on the Earth's surface, the shortest distance between them is along a Great Circle route. This is because a Great Circle route follows the shortest possible path on the curved surface of the Earth, rather than following a straight line on a flat map.
For example, when you see a direct flight path from New York to Tokyo on a flat map, it might appear to be a straight line, but when you look at the same route on a globe, you'll notice that the route follows a curved line. This is because the shortest path between these two cities is along a Great Circle route.
Therefore, the correct answer is: Great Circle.
