The Permian period is known for the formation of huge coal deposits and widespread anoxia in the oceans, which led to the extinction of 90% of marine species. Additionally, the burning of vast coal reserves produced an enormous amount of methane, which created a "Great Dying" on land, where around 70% of terrestrial species went extinct.

Answer: B
 The Anthropocene period, which some scientists argue is a new geologic epoch caused by human activity, is characterized by significant environmental changes such as air pollution, deforestation, and climate change, that have caused widespread habitat destruction, and significant extinction events. Anoxic oceans and methane burning is also a potential concern in the future.

Note: The Devonian period is known for the first appearance of complex fish, and the Cretaceous period is famous for the extinction of the dinosaurs due to a meteor impact. There is no mention of anoxic oceans and methane burning in either of these periods in geological history.
