The correct answer is A. Many places are named using Native American words

Explanation:

Native American culture had an important influence on modern culture in the United States, including specific words, food, practices, among others. One of the most notable influences of this culture related to geography is the use of Native tribes words or similar to name different places, this is the case of states such as Alabama named after the Alibamu which was a native American tribe or Idaho which is suppose to be related to the Plain Apache word ídaahé which means enemy. Also, it occurred in parks and other places as the Denali National Park which is inspired on deenaalee the  word in Koyukon language spoken by Native Americans in Alaska and which means the tall one or the Niantic River in Connecticut inspired on the Niantic tribe which were called Nehantucket. Thus, a notable influence is the use of Native American words to name places.
