Quizplus · Accepted Answer

As ocean waters warm, the permafrost on oceanic mud could melt and release methane, which is trapped under the ice in the form of methane hydrates.

Answer: D
 Methane is currently trapped in permafrost in the arctic tundra. As the permafrost melts due to global warming, methane could be released into the atmosphere.

Therefore, the correct answer is D.
