Answer:
Water flowing west from the continental divide in the Idaho Rockies will eventually flow into Willamette River.
Option: (A)
Explanation:
- The Willamette River flowing from the state of Oregon accedes the water flowing out from the Idaho Rockies as the natural path that the water takes runs towards the west.
- After flowing perpendicularly across the state of Idaho, it runs further westwards and eventually meets the Willamette River which further flows towards the western coast to meet the Pacific Ocean.
