Which of the following is NOT considered a type of plagiarism?

• A. Incorrectly citing a source
• B. Using someone else's work without credit
• C. Using sources from a prior assignment
• D. Copying definitions without attribution

Answer: (C)

Using sources from a prior assignment is not considered a type of plagiarism because it typically involves your own work that you have already created. In academia, this is often referred to as "self-plagiarism," which occurs when a student reuses significant, identical, or nearly identical portions of their own previously submitted work without sufficient citation or acknowledgment. However, it is generally accepted in many contexts that reusing your own work is permissible, provided it is adequately cited when required.

In contrast, the other actions listed—incorrectly citing a source, using someone else's work without credit, and copying definitions without attribution—are all forms of plagiarism. They involve failing to give appropriate credit to the original authors or sources, which misrepresents someone else’s intellectual property as one’s own. Understanding these distinctions is key to academic integrity and proper citation practices.
