The most significant difference between the Articles of Confederation and the U. S. Constitution was in the

the constitution follows a bicameral system that has two houses at the parliament. when the articles of confederation had a unicameral system.

the navigation act prevented the colonies from exporting to countries other than britain and it prevented the importation of goods by other countries as well. so i believe the correct answer is d. other nations could not deliver goods to the colonies.

hope this .
