How can you cite sources in a verbal presentation to enhance credibility?

• A. Ignore sources and rely on personal authority.
• B. Cite sources only in the final written report.
• C. Use approximate numbers without attribution.
• D. Mention the source briefly, attribute data or quotes, and display a citation on slide or handout.

Answer: (D)

Citing sources during a verbal presentation strengthens credibility by tying what you say to evidence and giving the audience a way to verify it. The best approach is to mention the source briefly when you present a fact or quotation, attribute data or ideas, and display a citation on the slide or in a handout. This keeps your talk smooth while still making your evidence traceable. For example, you might say, “According to Smith (2020), renewable energy accounted for 40% of the grid in 2019,” and show a brief citation on the slide footer or in the handout bibliography. This practice signals that you’re basing claims on reliable work, helps prevent misattribution, and allows the audience to locate the original source themselves.

Ignoring sources or relying on personal authority, citing only in a final written report, or presenting numbers without attribution would undermine credibility and mislead the audience. Brief, on-the-spot attributions with visible citations strike the right balance between conversational flow and scholarly transparency.
