Which of the following is NOT an example of denied powers?

The correct choice demonstrates an understanding of the concept of denied powers in the context of government authority. Denied powers refer to actions or authorities that are specifically prohibited by the Constitution for both state and federal governments.

Regulating interstate commerce is actually an enumerated power granted to Congress by the Constitution, specifically addressed in the Commerce Clause. This power enables the federal government to regulate trade and commerce that crosses state lines, signifying its importance in maintaining a functional national economy. In contrast, the other options listed represent actions that are prohibited or restricted:

• Taxation without representation is a historical grievance and is not permissible under a representative government, thus reflecting the principles that the government cannot impose taxes without giving the governed a voice.

• Granting titles of nobility is explicitly forbidden by the Constitution, ensuring a level of equality among citizens and preventing the establishment of a hereditary aristocracy.

• Establishing post offices is an enumerated power granted to Congress, but with a different context; it is not universally denied like the other two.
