When writing a report, which of the following enhances its credibility?

Including citations and references to credible sources is a fundamental practice that significantly enhances the credibility of a report. By referencing authoritative materials, the writer demonstrates that their findings and arguments are supported by established knowledge and research. This not only provides a solid foundation for the report's claims but also allows readers to verify the information and explore the sources further, fostering trust in the author's expertise and the reliability of the content presented.

Incorporating citations also acknowledges the work of other researchers and scholars, which is vital in academic and professional environments. It shows that the author has engaged with the existing literature on the subject, rather than relying on personal opinion or isolated examples. This thoroughness contributes to a more persuasive and respected document, appealing to the audience's need for reliable information.

The other options undermine credibility by either promoting misleading information, relying on unverified anecdotes, or obscuring meaning with complex language. They do not provide the necessary support for claims, ultimately detracting from the overall quality and authority of the report.
