Which term refers to using others' work without proper attribution?

• A. Plagiarism
• B. Bibliographic Citation
• C. MLA Style
• D. Librarians

Answer: (A)

Plagiarism is using someone else's work or ideas without giving proper credit. It covers copying text verbatim without quotation marks and a citation, or rewording someone else's thoughts too closely without acknowledging the source. In schools and libraries, this breaches integrity and can have serious consequences, so attributing sources with citations is essential. A bibliographic citation is simply the record of a source used; MLA Style is one widely used format for presenting those citations; librarians are professionals who assist with finding and evaluating sources. Because the description points to presenting others' work as your own, the term that fits best is plagiarism.
