Which of the following is NOT a normal category of inventory?

The correct response indicates that "Non-tangible assets" is not a normal category of inventory. In accounting and inventory management, traditional categories of inventory typically consist of raw materials, work in process, and finished goods. These categories reflect the stages of production: raw materials are the basic inputs used to create products, work in process refers to products that are still being manufactured and not yet completed, and finished goods are completed products ready for sale.

Non-tangible assets, on the other hand, do not fit within this framework of inventory. They refer to intangible items that do not have a physical presence, such as intellectual property, goodwill, or brand recognition. Since inventory is focused on tangible goods that a company produces or sells, non-tangible assets are classified differently in financial statements and accounting, primarily under long-term assets or intangible assets, rather than within inventory categories.
