It’s B, gaming territories by treaty or war. Let me explain:
Throughout the years mainly in the 1800s-1870s, the USA has numerous treaties and some wars that gained them the territory they have today. An example of a treaty is the Louisiana purchase of 1803, and a war example is the Mexican-American war, which gained them most of their territories out west.
The first answer is incorrect because the US mainly paid with their own money on these land purchases, and the last one is also incorrect because the US bought by the Louisiana territory, not sold it (and that would actually lose them territory).
Hope this helps! (Please consider branliest, because as of writing this post, I’m 5 away from the Virt rank, thanks!)

The United States, along with Canada, joined with ten European countries in signing the North Atlantic Treaty in 1949.

The ten original Western European members of NATO were the United Kingdom, France, Belgium, the Netherlands, Denmark, Norway, Portugal, Italy, Iceland, and Luxembourg.
The citizens of the empire in Constantinople believed that they were the citizens of Rome. Even after the city of Rome fell in the Fifth Century, contemporary Romans felt that the empire survived by moving East. In this way, Eastern and Western Rome were one in the same. It was only later that historians designated the title Byzantine Empire to the remaining remnants of the Roman Empire in the East.
