Target entity: Arctic drainage basin
Context triple: [Hudson Bay region, partOf, Arctic drainage basin]

A. Canada Basin
The Canada Basin is a deep, remote submarine basin in the Arctic Ocean, located north of Alaska and Canada, known for its extreme depths, perennial sea ice cover, and importance to polar oceanographic research.
B. Arctic region
The Arctic region is the Earth's northernmost polar area, characterized by extreme cold, sea ice, tundra landscapes, and unique ecosystems adapted to long periods of darkness and light.
C. Hudson Bay region
The Hudson Bay region is a vast, sparsely populated area in northeastern Canada centered around Hudson Bay, known for its subarctic climate, Indigenous communities, and historical role in early European exploration and the fur trade.
D. Hudson Bay
Hudson Bay is a vast inland sea in northeastern Canada, known for its subarctic climate, extensive ice cover, and crucial role in regional ecosystems and Indigenous cultures.
E. Beaufort Sea
The Beaufort Sea is a marginal sea of the Arctic Ocean off the northern coasts of Alaska and Canada, known for its sea ice, harsh climate, and significant oil and gas reserves.
F. None of above. chosen
G. Unsure - the case is ambiguous/there is not enough information to decide.
