When Congress finally adopted the Articles of Confederation, they agreed that western lands would be a)Held off from settlement for 10 years following the end of the American Revolution.
b) Divided proportionally among the states based on population at the end of the American Revolution.
c)Divided equally among the states at the end of the American Revolution.
d)Ceded to the new federal government to organize and sell as it liked.

D.

Explanation:

Article of Confederation was the article that was laid by the States after it declared independence from Britishers. The article was not not perfect but to amend it required urgency to prevent other countries from foreign invasion.

The article was read out by Franklin before the Congress on July 21, 1775. The claims of ratifying were holdout by Maryland, Delaware and New Jersey because they wanted other states to first give up their western land claims, which was agreed by all states by March 1, 1781.

So, according to the Article of Confederation, all states agreed to cede their lands to the federal government to organize it and sell accordingly.

Thus the correct answer is option D.
