The correct answer is C. When it is used to support or refute something
Explanation:
The word "evidence" is used to refer to any type and piece of information that is used as part of arguments or in the process of supporting or refuting a claim. Due to this, evidence can be found in almost any source including books, research studies, documentaries, surveys, etc. although some types of evidence are considered to be more reliable than others. This implies a piece of information is considered as evidence only in the case the information is used to prove something especially in terms of showing some idea is true or false or to support or refute it (Option C).
