The correct option is B Tundra region
The
northern part of the continents within the polar region is known as the Tundra region. Tundra regions are found in the northern
and southern hemispheres between the ice-covered poles and the coniferous
forests. In the north, this biome stretches across northern Canada and Alaska,
Siberia and northern Scandinavia, on or close to the Arctic Circle. There are
also areas of tundra in coastal Antarctica.
