Which of the following is considered plagiarism?

written communication that damages a person’s reputation
copying materials from a source text, supplying proper documentation, but leaving out quotation marks
spoken defamation to damage a person’s reputation
giving the author or creator of an original work exclusive rights to that work

The correct answer is B. Copying materials from a source text, supplying proper documentation, but leaving out quotation marks

Explanation:

Plagiarism occurs if you take ideas or information from a source or author without acknowledging this authorship. This is unethical and disrespectful because you are showing the author's ideas as yours. Examples of plagiarism include copying part of the material or source without using quotation marks and adding a citation, and paraphrasing or summarizing information without adding a proper citation.

According to this, the situation that would be considered plagiarism is "Copying materials from a source text, supplying proper documentation, but leaving out quotation marks" because in this case the original author is not being acknowledged due to the lack of quotation marks and a proper citation such as the authors last name, date of publication and page number. Also, citations and similar are require as only proper documentation is not enough to show to whom the ideas belong.
