The correct answer is option C.
An EIS (Environment Impact Statement) comes under U. S. environmental law, it refers to a document needed by the NEPA (National Environmental Policy Act) for some kinds of activities that substantially influence the quality of human surrounding.
It is a tool for making decisions. It illustrates the negative and positive environmental influences of a proposed activity, and it generally also considers one or more activities that may be selected rather than the activity illustrated in the EIS.
