Correct Answer: A — Parallel
Explanation:
Parallel. Orthographic projection is a parallel projection technique in which the parallel lines of sight are perpendicular to the projection plane. Unlike perspective projection where the observer is at a finite distance, in orthographic projection the observer is at infinity, making all projection lines parallel to each other.
