Explanation:

First Question

The Articles of Confederation had no executive branch to enforce laws. The Constitution's creation of an executive branch (President and related) addressed this. The Bill of Rights is about individual rights, Electoral College is for presidential elections, and trial by jury is a judicial right—none relate to law enforcement.

Under the Articles, states had their own trade rules, causing conflicts. To resolve this, the Constitution gave Congress power to regulate interstate commerce. The national government couldn’t tax exports (Articles limited taxation), states could coin money (which was a problem but not for interstate commerce), and Congress didn’t control all trade routes (states had more trade power).

Popular sovereignty is the principle that the people are the ultimate source of authority in a government. Federal supremacy is about federal law over state law, checks and balances is about branch powers, and judicial review is about courts reviewing laws—none match "people hold ultimate authority" like popular sovereignty.

Answer:

A. Creation of an executive branch
