A document stating the principles of a political party

• A. State's Rights
• B. Nullification
• C. Platform
• D. Fugitive

Answer: (C)

This is about the formal statement a political party produces to lay out its beliefs and the policies it plans to pursue. A platform is a written document that lists the party’s principles, goals, and proposed positions on major issues, signaling to voters what the party stands for and what it would aim to implement if elected.

The other ideas aren’t about a party’s official principles in document form: states' rights refers to the idea that states should have power relative to the federal government; nullification is a theory that a state can invalidate federal laws; and a fugitive is someone who is fleeing, often used in historical contexts related to fugitives and laws. So the description best fits a platform.
