Which of the following is NOT a legal use of copyrighted work?

• A. Assignment
• B. License
• C. Plagiarism
• D. Royalty

Answer: (C)

Plagiarism is identified as the correct answer in this context because it involves the unethical practice of using someone else's work or ideas without proper acknowledgment or permission, presenting them as one's own. Unlike assignment, license, or royalty, which are legal mechanisms through which copyrighted material can be used or compensated, plagiarism fundamentally undermines the rights of the original creator and does not conform to legal frameworks regulating copyright. Copyright laws are designed to protect creators' rights, allowing for certain uses through assignment (transfer of rights), licensing (permission under specified conditions), and royalties (payments for use of the work). Plagiarism, however, disregards these protections and is not sanctioned under copyright law, making it illegal and unethical in both academic and professional contexts.
