Correct answer: C
Correct order: Construct world-coordinates scene using modeling-coordinates transformations; Convert world-coordinates to viewing coordinates; Map viewing coordinates to normalized viewing coordinates using window - viewport specifications; Map normalized viewpoint to device coordinates.
Construct world-coordinates scene using modeling-coordinates transformations.
Convert world-coordinates to viewing coordinates.
Map viewing coordinates to normalized viewing coordinates using window - viewport specifications.
Map normalized viewpoint to device coordinates.
Why this order:
Modeling must build the scene in world coordinates before any camera/view transforms.
Viewing transformations position and orient the scene relative to the camera; they depend on the world-coordinate scene.
Normalization (window/viewport mapping) converts the viewing volume to a canonical coordinate range suitable for consistent projection and clipping.
Device mapping is last because it scales and translates normalized coordinates into actual screen/pixel coordinates.
