Which of the following is not a cost associated with the use of natural resources?

A. environmental

B. energy

C. renewable

I think the answer is a but I am not sure

Option C, Renewable

Explanation:

Renewable is a term that defines the type of energy which exist in enormous amount and can be used again and again. Thus it can not be a term which can be linked with cost of using a natural resource.
