Which level of government has powers such as defence, post office, currency, and criminal law?

• A. Diverse
• B. Bias
• C. Red River Resistance
• D. Federal Powers

Answer: (D)

In a federal system, powers that affect the entire country and require one set of rules across all regions are handled by the national or federal level. Defence, the post office, currency, and criminal law fit this because they need uniform policies and national institutions to work together—diverging rules across provinces would create chaos in security, money, mail, and justice. That’s why these areas are assigned to the federal government: to keep the country united and functioning smoothly. The other options aren’t about a level of government at all—one refers to a historical event, another is not describing how government levels operate—so they don’t fit as the correct description.
