The hazardous waste listings consist of all of the following except:

• A. K list
• B. U list
• C. F list
• D. Z list

The concept being tested is which categories make up the official hazardous waste listings under RCRA. The listing families are F lists (wastes from common non-specific sources like spent solvents), K lists ( wastes from specific industries or processes), and P and U lists (discarded commercial chemical products that are acutely hazardous or toxic). A Z list does not exist as part of these RCRA hazardous waste listings, so it doesn’t belong. That’s why the option named Z list is the correct exception; the other three are real listing categories.
