Which pair of freshwater bodies is among Canada's major freshwater resources?

• A. Hudson Bay and Arctic Ocean
• B. Bay of Fundy and Gulf of St. Lawrence
• C. Great Lakes and St. Lawrence River
• D. Pacific Ocean and Atlantic Ocean

Answer: (C)

The main idea is recognizing Canada's largest sources of freshwater: a vast lake system and the river that drains it. The Great Lakes form the biggest freshwater lake complex in the country, supplying a huge amount of clean water. The St. Lawrence River then serves as the main outlet from those lakes to the Atlantic, linking the freshwater system to the ocean and supporting transportation, hydroelectric power, and downstream water supply. The other options are saltwater bodies or coastal bays, not primary freshwater resources for Canada. So the pairing of the Great Lakes with the St. Lawrence River best represents Canada's major freshwater resources.
