The correct answer is D. Motion and transportation . In the CSSBB materials, a spaghetti diagram is used to show the physical flow of people, materials, or information through a workspace or process. Because it traces actual paths and movement, it is especially useful for exposing unnecessary walking, backtracking, handoffs, and poor layout. Earlier CSSBB references describe spaghetti diagrams as tools for showing flow, which directly supports identifying movement-related waste.

The waste categories in the CSSBB source include both motion and transport as separate forms of muda. Motion refers to extra human movement such as walking, bending, reaching, or repeated motions, while transport refers to the movement of materials through forklifts, conveyors, trucks, or inefficient layouts. A spaghetti diagram can reveal both kinds of waste because it visually shows where people and materials travel more than necessary. The other answer choices involve wastes that are not best exposed by path mapping. Therefore, the best verified answer is D. Motion and transportation .
