Final answer:
Option B (60°N, 100°W) is the closest to the center of the Arctic Tundra Biomes, as the tundra spans multiple countries and longitudes, with the Arctic Circle at around 66.5 degrees North.
Step-by-step explanation:
The latitude and longitude for the center of the Arctic Tundra Biomes would lie within the Arctic Circle, which is a line of latitude at approximately 66.5 degrees North, marking the southernmost point of the Arctic region. However, the Arctic tundra extends beyond this latitude and is not confined to a single point. Therefore, no single answer would be completely correct as the Arctic tundra spans several countries and multiple longitudes. For the purpose of this question, the closest option to the center of the Arctic Tundra Biomes would be Option B) 60°N, 100°W, which places it within the broad range of the tundra region in Northern Canada. Options A, C, and D are not centered within the tundra biome. While the Arctic Circle itself is positioned at around 66.5°N, which is close to Option A (90°N is actually the North Pole and not where the majority of tundra is located), and D (75°N, 160°E) is also within the Arctic zones, 60°N is a typical latitude for the spread of the tundra.
