Answer:
A. Congress could tax goods coming into the country but not goods going
Step-by-step explanation:
The North-South Compromise of 1787, was a "Compromise Agreement" of sorts happening between delegates of the Northern States and the Southern States, the purpose of this compromise between the north and south, they had many goals,
Such being to end slavery, which, didn't work, taxation without representation and lastly the regulation of trade, the United States was still being formed at the time and so was the constitution, the British were still on there tails despite the United States being successfully declared independent.
Now, C. Is out of the question because 1. Slavery didn't end until about 100 or so years later, and 2. the question is regarding foreign trade and taxes`, which leaves us with A and B and D.
The idea that congress would control all trade "Between States" was, actually a legitimate idea at the time, the founding fathers were divided into thinking either if the federal government should have most of the power (Authoritarian),or as they called it, Federalism, and the other half thought about the dividing of powers and states (Anti-Federalism). Which is the current system we use, later congress eventually this power over trade, through the Commerce Clause of 1887, but not through the North-South Agreement of 1787, so we can X out B. (A and D are left)
We don't really need an explanation for D, since the power to tax external trade also came from the Commerce Clause of 1887, but It was fiercely debated that Congress would have power to tax goods coming in and out, eventually, that clause of the North-South Compromise was "Edited"
I Hope this helps on whatever your doing!
