Which group is exempt from the provisions of the Constitution according to its text?

The correct answer is "None of the above" because the Constitution applies universally to all groups specified within its text. The Constitution does not provide exemptions for any particular group in its fundamental provisions. Citizens of the United States, elected officials, and judicial representatives are all subject to the same constitutional laws and protections.

The Constitution's framework is designed to ensure that both the rights it bestows and the responsibilities it imposes are applicable across the board, thereby promoting equality under the law. This includes rights such as due process and equal protection which cannot be selectively applied based on an individual’s position or status. Therefore, saying that "none of the above" are exempt reflects the inclusive nature of the Constitution's authority and its intended reach over all individuals within the jurisdiction of the U.S. legal system.
