Which of the following represent plagiarism?

Plagiarism is represented when someone copies the words or ideas of another and claims that it is their original work. Citing the source of an idea or quote is one way to avoid plagiarism in personal work.

Putting one's name on another person's work, using another person's ideas without giving that person credit, forgetting to use quotation marks around a quote or not citing the source of a quotation are all forms of plagiarism. To prevent plagiarism when writing a paper, writers must remember to always cite their sources. There are different citations systems; writers must use the system that is recommended or required by their editors.
