An Order-in-Council signed by King George III on July 20, 1764, said that the boundary between New Hampshire and New York is the west bank of the river. The order was intended to settle a dispute between New York and New Hampshire in which each claimed the territory that later became the state of Vermont. The disputed territory had been governed for 15 years as a de facto part of New Hampshire, but the king's order awarded it to New York. On January 15, 1777, Vermont issued its declaration of independence, creating the independent Vermont Republic. On August 20 and 21, 1781, Congress expressed conditions that must be met before the then-still unrecognized but de facto independent state could be admitted into the Union. Among the conditions was that Vermont must give up its claims to territory east of the river. On February 22, 1782, Vermont's legislature complied, and the Supreme Court's opinion in 1933 cited that act.
I might be wrong but I believe it's either A or D.
