Answer:
d. Converge parallel lines at the horizon to create a linear perspective.
Step-by-step explanation:
To create an illusion of three-dimensions, a linear perspective is the best way to achieve this. A linear perspective is a system used by artists and other game developers to create an illusion of depth on flat surfaces. When using this technique, all parallels lines are made to converge at a single vanishing point at the horizon, thereby giving it a three-dimensional look.
