Answer 1

The "great dying," also known as the Permian-Triassic extinction event, is thought to have been partially caused by bacteria producing large amounts of toxic methane. This event led to significant environmental changes, including widespread anoxia in the oceans. While other factors, such as volcanic activity and potential asteroid impacts, may have also played a role, the major factor related to the options given would be the bacterial production of methane.
