The hierarchy of components, their description, and the quantity of each required to make one unit of a product are documented on: A. an engineering drawing. B. a bill of material. C. a route sheet. D. a work order. E. a group technology listing.

The hierarchy of components, their description, and the quantity of each required to make one unit of a product are documented on a bill of material.

Option B

Explanation:

"A bill of materials" is an elaborated list of components or raw materials. It is presented in "hierarchical format or order", with highest level means showing "final product" and the bottom level means showing individual materials.

"An engineering drawing" is a kind of "technical" drawing used for clearly representing the engineer items requirements.

A route sheet means listing the production operations, their sequence and also the equipment and special tooling.

"A work order" is a "document" that provides the information about maintenance of task and presents a schedule for completing that task.

"Group technology" is a "manufacturing technique" in which the parts having similarities with respect to manufacturing process and geometry are manufactured in single location using small number of process and machines.
