Which of these is a drawback associated with using oil? a. human error can lead to oil spills. b. surface mining can cause earthquakes. c. shale rock deposits can release gas. d. acid mine drainage can pollute waterways.

A drawback is a disadvantage, makes something less acceptable. 

I know this is a hard one because they all seem like drawbacks. 

The question most directly states 'using' oil, not 'getting' oil. 

I would go with "A" for this very reason. That is not about getting the oil, and everything else varies directly with that.

I hope this helps!
