Final answer:
Citing is the act of identifying the source of a quotation or an idea. Quoting and plagiarizing are related but different concepts.
Step-by-step explanation:
Identifying the source of a quotation or an idea is called citing. Citing involves giving credit to the original author or source by including a citation or reference in a proper format, such as MLA or APA.
Quoting, on the other hand, refers to directly using someone else's words or ideas and indicating them with quotation marks. Plagiarizing, however, is the act of using someone else's work without proper attribution, which is considered unethical and can lead to serious academic consequences.
In summary, the correct answer to the question is citing.
