The International Date Line is an imaginary line that runs mostly along the 180° longitude line in the Pacific Ocean. It serves as the dividing line between two consecutive calendar days. The correct answer to the question is option 2, which states that the International Date Line passes through the Bering Strait.

Option 1, Baffin Bay, is incorrect. Baffin Bay is located on the eastern coast of Canada, and the International Date Line does not pass through this area.

Option 3, Denmark Strait, is also incorrect. The Denmark Strait is the stretch of water that separates Greenland from Iceland. The International Date Line does not pass through this area.

Option 4, Hudson Bay, is also incorrect. Hudson Bay is a large body of water in northeastern Canada, and the International Date Line does not pass through this area either.

In summary, the correct answer is option 2, the Bering Strait, as the International Date Line runs through this area.
