How did the u. s. constitution address a weakness of the articles of confederation?

a. the constitution allowed the states to exercise more power than the articles of confederation did.

b. the constitution gave more power to the federal government than the articles of confederation did.

c. the constitution outlawed slavery, while the articles of confederation allowed it.

d. the constitution required unanimous support to pass laws, while the articles of confederation only required majority support.

B.) The Constitution gave more power to the federal government than the Articles of Confederation did.

Under the Articles, the federal government had power to declare war, make alliances, and a few other duties.  The main power lied in the states' hands.  The Constitution made the federal government have more power.  It also created 3 branches of government (executive, legislative, and judicial) rather than only one (legislative).

Hope this helps.
