Final answer:
Ling including the author's name of a source in her report is an example of citing an online source, as it gives credit to the original author and avoids plagiarism.
Step-by-step explanation:
The scenario that describes a student citing an online source in his or her work is: D. Ling includes the name of a source's author in her report. When a student cites a source, they are acknowledging the original author of the information they are using in their own work. This citation can take the form of in-text citations and external bibliography or reference list entries.
The citation usually includes the author’s name, the title of the source, and often additional publication details, such as the date of publication and the URL or DOI (Digital Object Identifier) in the case of online sources. For example, if Ling uses a piece of information or a quotation from an online article, she needs to provide an in-text citation and a corresponding reference list entry so that her readers can locate the original source themselves. This practice not only gives credit to the original author but also enhances the credibility of Ling's report. Ling's action is a key aspect of avoiding plagiarism, as it clearly distinguishes her own ideas from those she has borrowed from other sources.
