Final answer:
A) Expressed powers
The National Government exercises its expressed (enumerated) powers when regulating immigration, as specified in the Constitution. The Tenth Amendment distinguishes reserved powers for state governments, which are separate from federal powers like expressed, implied, and inherent.
Step-by-step explanation:
When the National Government regulates immigration, it is exercising its expressed powers. The Constitution specifically lists the power to make rules for immigration and naturalization as one of the enumerated powers given to the national government. Therefore, the correct answer to the question is A) Expressed powers.
The Tenth Amendment created a class of powers exclusive to state governments, referred to as C) reserved powers. These powers are distinct from the expressed (enumerated), implied, and inherent powers of the federal government. Reserved powers are those that the Constitution does not delegate to the national government nor prohibit to the states.
