Answer:
Correct answer is C: Each state had one vote and could not agree on important issues.
Explanation:
Option A is not correct as Congress didn't have enough authority to impose taxation system on the states.
Option B is not correct as this wasn't also something that Congress was able to do.
Option C is correct as every state had one vote, no matter what was the size of it. Therefore larger states were unsatisfied.
