A

A-4, B-3, C-2, D-1

B

A-5, B-3, C-1, D-2

C

A-5, B-4, C-1, D-3

D

A-3, B-1, C-4, D-2

Correct Answer: Option B

Explanation

1. The task is to match the rivers labeled A, B, C, D on the map (presumably of North America) with the names provided in the list. 2. Identify the rivers from the list and their general locations: 1. St. Lawrence: Flows from Great Lakes to Atlantic, forming part of US-Canada border. 2. Orinoco: Major river in South America (Venezuela/Colombia). *Likely irrelevant if map is North America.* 3. Mackenzie: Major river system in northwestern Canada, flowing to the Arctic Ocean. 4. Amazon: Major river in South America. *Likely irrelevant if map is North America.* 5. Yukon: Flows through Alaska (USA) and Yukon territory (Canada) to the Bering Sea. 3. Match labeled rivers on a typical North America map: A (Far northwest): Likely the Yukon River. B (Central north, flowing north): Likely the Mackenzie River. C (Northeast, from Great Lakes): Likely the St. Lawrence River. D (Southeast USA/Gulf): Could be Mississippi, but not listed. If map includes northern South America, could be Orinoco/Amazon. Assuming strictly North America, D is problematic or represents a river not in options 1, 3, 5. 4. Let's assume the map includes the relevant rivers and re-evaluate based on options, considering the provided answer is B (A-5, B-3, C-1, D-2). A-5: Map label A corresponds to Yukon (5). Correct. B-3: Map label B corresponds to Mackenzie (3). Correct. C-1: Map label C corresponds to St. Lawrence (1). Correct. D-2: Map label D corresponds to Orinoco (2). This implies the map included the northern tip of South America, and D represented the Orinoco. 5. Therefore, the matching based on answer B is A-Yukon, B-Mackenzie, C-St. Lawrence, D-Orinoco.
