Which of the following explains why the Articles of Confederation were weak? A: The Congress taxed the states too heavily after the war
B: The Congress heavily restricted trade with trade
C: Each state had one vote and could not agree on important issues
D: Each state had two votes in the Congress, but only certain states could use both at the same time

Correct answer is C: Each state had one vote and could not agree on important issues .

Explanation:

Only option C is correct as every state, no matter what their size was had the possibility to put one vote. Of course this created disbalance in the country while bringing certain decisions.

A is not correct as the Congress didn't had ability to impose taxes to states.

B is also not correct as this wasn't something that Congress was able to impose.

D is not correct because each state had one, not two votes.

i think it is the third one.
