B

Explanation:

When writing a paper it is important that the research you chose to use is on topic with what you a writing about. Although having a credible source is an important factor in determining what evidence you use, there are plenty of credible studies or sources that will be completely unrelated to the topic of your paper. Therefore, source must be relevant to the topic of your paper in order to be a valid point in your argument.
