Solution
The range is defined as:
Range = Max - Min
For this case we can conclude that the best solution would be:
B, C
Consider the attached picture. It represents a vector, centered in the origin with angle 41.7 degrees, and a circumference with radius 25, centered in the origin.
As you can see, the horizontal and vertical components of the vector correspond to the lengths of segments OD and OC, respectively.
You might recognize this scenario from you trigonometry class: if the circle had radius 1, we would have
Since the circle has radius 25, we have to scale those coordinates:
