Which statement best explains how the Constitution addressed a weakness
 in the Articles of Confederation?
 A. The federal government did not have enough power to enforce its
 laws, so the Constitution gave the federal government more power
 than the states.
 B. State militaries were more powerful than the federal army, so the
 Constitution required each state to send a percentage of its
 population to defend the country.
 C. States were able to make individual trade agreements with foreign
 countries, so the Constitution made it illegal for a state
 representative to meet with a foreign diplomat.
 D. The federal government was inefficient because its power was
 divided into three branches, so the Constitution created a single
 federal government office led by the president.
