Answer:
Option A. Fraser.
Step-by-step explanation:
If a world map is analyzed with a focus on Canada, one can discern that the Great Divide of the Continental Divide leaves the Mackenzie, Mississipi, and St. Lawrence on the east side of the division. In contrast, the Fraser River, located in British Columbia, Canada, lies on the west side of the divide along with the Yukon River -- which begins in northern British Columbia, and goes along Yukon Territory.
