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.
