Final answer:
The U.S. Constitution prohibits suspending habeas corpus during peacetime, creating a national religion, and passing ex post facto laws, but allows passing "necessary and proper" laws and borrowing money for the government.
Step-by-step explanation:
The Constitution of the United States delineates the powers of the government and explicitly prohibits certain actions to protect the rights and liberties of individuals. Among the prohibited actions, both the federal government and the states are restricted from suspending habeas corpus during peacetime, which is a person's right to appear before a judge to determine the legality of their detention; creating a national religion, which would infringe upon the freedom of religion; and creating a law ex post facto, meaning laws that criminalize actions retroactively. These protections are outlined in Article I, Sections 9 and 10 of the Constitution and are further reinforced by the Bill of Rights and subsequent amendments.
On the other hand, the Constitution does not prohibit the federal government from passing "necessary and proper" laws—a power granted by the Necessary and Proper Clause—which allows Congress to pass laws it deems necessary to carry out its enumerated powers. It also does not prohibit borrowing money for the government, which is an essential function of the federal government's fiscal responsibilities.
To summarize, actions (b) borrowing money for the government and (a) passing "necessary and proper" laws are permitted by the Constitution, while actions (c) creating a national religion and (d) creating a law ex post facto are prohibited by the Constitution.
