Explanation:

The acquisition of thousands of square miles of new territory only exacerbated the political crisis in Washington over whether slavery would be allowed there. A group of Northern Democrats attempted to prohibit the spread of slavery into the formerly Mexican lands but fell short of votes in the United States Senate. The issue of slavery’s expansion was at the center of the presidential campaign of 1848, and the Free Soil Party, a new antislavery party, polled more than 9 percent of the vote. Politicians in Washington made a final attempt at a compromise in 1850, passing legislation that admitted California as a free state while at the same time enacting a stronger fugitive slave law to appease Southerners.

Hope this helps

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 .
