B. To discuss trade problems among the states.
Step-by-step explanation:
The Annapolis Convention was the meeting where five states met and talked about the Articles of Confederation. The Articles of Confederation was very weak and gave no power to the national government, this made it so they couldn't enforce laws, tax citizens, or regulate trade. Colonists thought this would be good at first, as they were scared the government would abuse power just like Great Britain did to them, but there were major problems. The Annapolis Convention was about trade issues that were abundant due to the Articles of Confederation, trade was not being regulated properly among the states due to the weak national government.
