A credible source is one that can be trusted and relied upon to provide accurate and reliable information. Credible sources are typically well-researched, objective, and supported by verifiable evidence.

It is important to use credible sources when conducting research or seeking information to ensure the accuracy and reliability of the information being gathered.

A credible source is one that is trustworthy. Option c) -- "trustworthy" -- is the correct answer.

To determine if a source is credible, you need to evaluate its reliability and reputation. Here are some steps to help you assess the credibility of a source:

1. Consider the author: Investigate the qualifications, expertise, and experience of the author. Look for their education, professional affiliations, and any previous research or work they have done on the topic.

2. Examine the publication or website: Determine if the publication or website has a reputation for accuracy, objectivity, and quality. Reliable sources often include academic journals, reputable news organizations, or well-established institutions.

3. Check for citations and references: A credible source will provide proper citations and references to support its claims. Look for sources that have been peer-reviewed or have gone through a rigorous editorial process.

4. Evaluate bias: Assess the potential biases in the source. A credible source should present information objectively, without favoring any particular group or viewpoint. However, it's essential to note that even credible sources can have some bias, so it's important to consider multiple perspectives.

By following these steps, you can determine if a source is credible and trustworthy, ensuring that the information you gather is reliable and accurate.
