The correct statement is "It caused many organisms to die off" because oxygen was toxic to them.

Option (b) is correct.

The Great Oxidation Event refers to the period of time approximately 2.4 billion years ago when oxygen began to accumulate in the Earth's atmosphere due to the evolution of photosynthetic organisms like cyanobacteria.

This event had a significant impact on the evolution of life on Earth, as the presence of oxygen allowed for the evolution of aerobic respiration, which is much more efficient than anaerobic respiration. However, the sudden increase in oxygen also caused many anaerobic organisms to die off because they were unable to tolerate the presence of oxygen,

In many countries, the government is organized into different levels of authority, including national, provincial/state, and local/municipal governments. Each level of government has a unique set of responsibilities and powers that are designed to address the needs and interests of civil society.

National governments are responsible for setting policies and laws that affect the entire country. They are typically responsible for issues such as national security, foreign policy, economic regulation, and social welfare programs. National governments have the power to tax citizens and businesses, regulate trade and commerce, and provide funding for important public services such as education, healthcare, and infrastructure.

Provincial or state governments are responsible for implementing policies and laws that affect their respective regions. They typically have the power to regulate local industries, provide funding for regional infrastructure projects, and manage social welfare programs.

Local or municipal governments also have the power to levy taxes on citizens and businesses within their jurisdiction.

Each level of government plays an important role in addressing the interests of civil society. National governments are responsible for creating policies that affect the entire country, while provincial or state governments focus on regional issues. Local or municipal governments are responsible for addressing the needs of individual communities. By working together, these different levels of government can ensure that civil society is well-served and that the needs of all citizens are met.
