The correct answer is C) A man wants to use national currency to buy a horse in Maryland.
Under the Articles of Confederation, America's first constitution after becomin independent from Great Britain, each state had the ability to coin their own money. This meant that each state had the chance to develop a unique currency. As you could imagine, this made trade between states extremely difficult. Along with this, there was no consistency among the state currencies and the national currency at this time. This is one of the many flaws that would be fixed by getting rid of the Articles of Confederation and ratifying the US Constitution.
