The correct answer is Oregon Country.
Manifest Destiny is the idea that America should controll all land from "sea to shining sea." More specifically, Polk and other individuals who believed in Manifest Destiny thought America should control all land between the Atlantic and Pacific Ocean.
In order to do this, America would have to gain land from other countries. One of these countries was Great Britian. Great Britain still had influence in North America, as they controlled part of the modern day Northwest (bordering the United States and Canada). Polk, who had an expanionist mindset, was focused on annexing this territory from the British and use the phrase "54'40 or fight!" to show that he would be willing to go to war with Britian for Oregon territory. Ultimately, war is avoided and the US gains up to the 49th parallel.
