Answer:
Option (D)
Step-by-step explanation:
The Palo Duro Canyon refers to the large canyon system of Texas that is present in the Texas Panhandle region adjacent to the Amarillo city and Canyon city. It forms the 2nd largest canyon, next to the Grand Canyon. It is usually about 200 km long and 10 km wide. The depth of this canyon varies from place to place, that ranges from about 250 to 300 meters.
In the given image, the arrow 4 in the northwestern side of the map is the closest to this Palo Duro Canyon, where the city of Kansas, Oklahoma, Nebraska, Canyon and Amarillo are adjacent to one another.
Thus, the correct answer is option (D).
