The correct answer is C) Alaska and Hawaii.
The United States acquired several new territories during the late 1800s. The two that eventually became states were Alaska and Hawaii.
Let's see the case of Alaska first. Alaska had been a territory that belonged to Russia since 1744. In 1867, the United States paid Russia $7,200,000 for Alaska. It was until 1959 that Alaska was made state.
In the case of Hawaii, the territory was a kingdom in 1883. One year later, sugar planters and missioners overthrew the Quen with the help of US marines. Then, the islands were part of the United States and became a state in 1959.
