Tom is writing a research paper about the use of nuclear energy around the world. He has located a source he wants to use: an article on the website of a nuclear power plant, written by Dr. Jane Nelson in 2016. Why might this source not be credible?

AThe article isn't related to the topic.
BIt might be out of date.
CIt is likely to be biased.
DThe author is not educated.

A credible source is one whose information can be trusted which is determined by different factors that include the date of the source as sources created a long time ago are not credible; the author of the source as only experts on the field are credible and the information provided in the source as this need to be supported by facts and be objective which means it is not biased or influenced by interests or personal judgments. In the case of the source found by Tom, this source deals with the topic Tom is interested; it is updated as it was written in 2016 and t also has a credible source because it was written by Dr. Jane Nelson- However, it is probable this source is biased because the website belongs to the nuclear power plant and therefore, it is more likely this source includes only positive information about the use of nuclear energy which means it is influenced by he interests of the nuclear plant. Thus, the reason that makes this source lack of credibility is that it is likely to be biased.
