After the navigation acts went into effect? british stopped shipping goods to colonies. the colonies began to export molasses. smuggling and piracy were stopped for good. other nations could not deliver goods to the colonies

I'm pretty sure that 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.

From there friends or an black doctor
