When you come across a source that you think may be biased, you should
a. not use the source at all.
b. accept the source as long as you agree with it.
c. check the source's credibility by using other sources.
d. use the source as long as you cite it in your work.
If you find a source to be biased and unreliable, you must check the credibility of the source, hence the answer is C. If you are trying to argue in favor of a certain viewpoint on an issue, a credible scientific source or news source must be used. Check who the authors and publishers are and what entities are funding the research.
