Final answer:
A firm's reputation is not a tangible resource as it is not a physical asset that can be touched or seen, unlike production equipment or distribution centers.
Step-by-step explanation:
The question revolves around identifying which of the listed options is not a tangible resource. Tangible resources are physical assets used in a company's operations.
A tangible resource is something like production equipment, distribution centers, and formal reporting structures. These all have a physical presence and can be touched or seen.
On the other hand, a firm's reputation is not a tangible resource as it cannot be physically touched or measured in the same way as equipment or buildings.
It is rather considered an intangible asset because it is a value derived from the perception of the firm by customers, suppliers, and other stakeholders.
