Which of the following black codes is a violation of the fourteenth amendment?
a. negroes could not sue whites in courts or testify against whites.
b. negroes may sue other negroes.
c. negroes could not carry a firearm.
d. negroes could not vote.

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 .
