Correct Option: C. Flexibility of the Constitution Explanation of the Correct Answer: A federal constitution is a foundational legal document that outlines the structure of government in a federal system, where power is divided between a central authority and various constituent units (like states or provinces). The key features of a federal constitution typically include:

1. Division of Power: This is a hallmark of federalism. In a federal constitution, powers are divided between the national government and the state governments. This division ensures that both levels of government have their own areas of authority, which helps to prevent the concentration of power in one entity.
2. Supremacy of the Constitution: In a federal system, the constitution is the highest law of the land. This means that any law or action taken by the government must comply with the constitution. If there is a conflict between state laws and federal laws, the constitution typically resolves this by establishing that federal law prevails.
3. Written Constitution: Most federal systems operate under a written constitution, which clearly outlines the powers and responsibilities of different levels of government. A written constitution provides clarity and serves as a reference point for legal interpretation and governance.
4. Flexibility of the Constitution: This is where the distinction lies. While some constitutions may be flexible, a federal constitution is generally characterized by rigidity. This means that it is not easily amended or changed. The rigidity is important because it protects the division of powers and the rights of the states against arbitrary changes by the central government.

In summary, the feature that is not typically associated with a federal constitution is flexibility. Federal constitutions are often designed to be stable and enduring, which is crucial for maintaining the balance of power between the federal and state governments. Explanation of the Other Options:

• A. Division of Power: This is a fundamental characteristic of federal constitutions. It ensures that different levels of government can operate independently within their own spheres of authority. This option is correct and a defining feature of federalism.
• B. Supremacy of the Constitution: This is also a key feature of federal constitutions. It establishes the constitution as the ultimate legal authority, ensuring that all laws and government actions are subject to constitutional review. This option is correct and essential for maintaining the rule of law in a federal system.
• D. Written Constitution: Most federal systems have a written constitution that clearly delineates the powers and responsibilities of the various levels of government. This written document serves as a legal framework for governance and is a common feature of federal constitutions. This option is correct and important for clarity and legal consistency.

Revision Summary:

• Federal constitutions are characterized by a division of power between national and state governments.
• They uphold the supremacy of the constitution, ensuring all laws comply with it.
• Most federal systems have a written constitution that outlines government structure and powers.
• Flexibility is not a feature of federal constitutions; they are typically rigid to protect the balance of power.
