What is the fundamental difference between ray tracing and rasterization as approaches to rendering 3D scenes?

A Rasterization always produces more physically accurate results than ray tracing B Ray tracing only operates on flat 2D vector artwork, while rasterization is limited to 3D meshes C Ray tracing simulates light ray paths through a scene to compute realistic reflections, refractions, and shadows, while rasterization projects geometry to the screen and approximates lighting D Ray tracing entirely removes the need for a frame buffer in the pipeline
