5. the top 10 list of environmental challenges in a repair shop includes all of the following, except: a) antifreeze, oil & other similar fluids b) batteries, tires, & paint booth filters c) floor drains, absorbents, and spills d) scrap metal and spare parts

I believe the answer is: C) Floor Drains, Absorbents, and Spills 

 Floor Drains, Absorbents, and Spills are the environmental challenges that might occur in a construction site, not a repair shop.
To avoid such problems, the local government usually would provide a strict regulation as safety measurements. And would fined the construction company that fail to pass their inspection.
