Answer:
The correct answer is C. The 10th Amendment limits the federal government's reach, and the 14th limits the state governments' reach.
Step-by-step explanation:
Both the Tenth Amendment and the Fourteenth Amendment are an integral part of the Constitution of the United States in its operative face, as they limit the federal and state governments in the exercise of their functions.
Thus, on the one hand, the Tenth Amendment establishes that the federal government may only exercise the rights and powers that have been expressly delegated to it by the States, which are ultimately the originators of sovereignty. Therefore, the federal government must respect the prerogatives of the States if they were not assigned to it.
In turn, the Fourteenth Amendment operates in the opposite way, establishing the Equal Protection Clause, which establishes that no state may discriminate or differentiate the citizens of the nation according to whether they are citizens of their state or not, with which it applies the protective criterion of the federal government to all states.
