The correct choice indicates that the vertical angle of attack is defined as being directed from a lower point to a higher point. In aviation and aerodynamics, the angle of attack refers to the angle between the oncoming air or relative wind and a reference line on the airplane or wing. A vertical angle of attack that moves from low to high suggests an upward orientation, which is relevant when discussing the lift generated by the wings of an aircraft. This upward angle is vital for understanding how changes in pitch and attitude can affect flight performance. An upward vertical angle leads to an increase in lift up to a certain point before potentially causing a stall if the angle becomes too steep.

In comparison, options describing angles directed from high to low or simply lateral movements (left to right or right to left) do not pertain to the concept of vertical angle of attack as they do not illustrate the crucial upward lift dynamics experienced during flight. Thus, recognizing that a vertical angle of attack directed from low to high is essential for grasping fundamental aerodynamic principles and the performance characteristics of aircraft.
