Answer:
The correct answer is option D. "Russia and Canada".
Explanation:
Russia and Canada are countries with extensive areas of arctic tundra conditions. These two countries could use these areas as a source of gas or methane hydrates since it have been demonstrated that tundra is rich in these gasses, which are trapped inside the ice. Unfortunately methane is a powerful greenhouse gas, and its release to the atmosphere is an environmental concern that rises from the climate change phenomena.
