A credible source of information is the reliable one, based on supporting evidence:
A study by researchers published on a university’s website is a credible source of information as its validity is authenticated by the fact that the university has allowed its appearance on its formal website which is viewed by millions of users every day.
Another credible source can be a book written by a scholar on the topic with examples supporting his viewpoint. It will carry his point of view based on research which can be used by the researcher to make his study. Such books have been used by researchers in the past to improve the development of a topic and carry on their research.
The two items that are credible sources of information for a research paper are the following:
A. A book written by a scholar on the topic.
D. A study by researchers published on a university website.
When writing, we should not use a source simply because it agrees with our claim/opinion. A source is only credible when it can actually prove what it claims to be true or not. Examples of credible sources are articles written by experts who have thoroughly studied the topic.
That is the case with options A and D. Those sources are credible because they were written by experts and because they have most likely been peer-reviewed. In other words, those are sources that contain serious information that has been proven true.
