Which of the following is used to address plagiarism and attribution in printed educational resources?

• A. Copy content from the Internet without attribution
• B. Include no bibliography
• C. Use only diagrams with no text
• D. Provide clear citation guidelines

Answer: (C)

Clear citation guidelines are essential in printed educational resources because they show exactly how to credit sources, quote or paraphrase, and list references in a consistent style. This directly helps prevent plagiarism by making the original authors and works visible, so readers can verify information and understand where ideas come from. It also models ethical use of material for learners and provides a reliable path to follow when researching or including borrowed content. To implement this, resources should include in-text citations or notes for figures and quotes, a bibliography or references section, and a consistent citation format (such as APA, MLA, or Chicago). Captions for images or diagrams should clearly indicate the source, and any permissions or licenses should be noted when needed. The other options miss the core mechanism for attribution: copying content without attribution hides sources; omitting a bibliography leaves readers without a way to trace origins; and using diagrams with no text still requires proper attribution for borrowed ideas or imagery.
