The correct answer is option 1: the West Coast of Greenland. Icebergs are large chunks of ice that have broken off from glaciers or ice shelves and are floating in the ocean. The production of icebergs primarily occurs in areas where there are large ice sheets or glaciers. Greenland, located in the North Atlantic Ocean, is home to the second-largest ice sheet in the world after Antarctica. The West Coast of Greenland is known for its abundant production of icebergs due to the presence of many glaciers and the calving (breaking off) of icebergs from these glaciers. These icebergs then travel into the open ocean and can sometimes be seen as far south as the Atlantic Ocean.

Option 2, the East Coast of Japan, is not correct as it is not a significant area for iceberg production. Japan is located in the Pacific Ocean, far away from areas where icebergs are commonly formed.

Option 3, the North Coast of Siberia, is also not correct. While Siberia does have some glaciers, it is not a major area for iceberg production. Siberia is located in the Arctic region, but it does not have as many large glaciers compared to Greenland or Antarctica.

Option 4, the West Coast of Africa, is also
