Purchased items are distinguished from manufactured items by A. stock location code B. product type code C. item number D. drawing number E. None of the above

The correct answer is C. item number.

Purchased items are distinguished from manufactured items by their item number. The item number is a unique identifier for each item in a company’s inventory. It is used to track the item’s movement through the company’s supply chain, from purchase to sale.

The stock location code is a code that identifies the location in a warehouse where an item is stored. The product type code is a code that identifies the type of product an item is. The drawing number is a number that identifies a specific drawing of an item.

None of these codes are unique identifiers for an item, and therefore cannot be used to distinguish purchased items from manufactured items.
