Answer:

C. make sure that any acceleration vector falls along one of the major axes of the coordinate system

Step-by-step explanation:

C. make sure that any acceleration vector falls along one of the major axes of the coordinate system

Since this simplifies calculations, otherwise you would have to break the acceleration vector into x and y components and so on.

Can become a mess...
