Which option ofers the events chronologically from earliest to latest

Question

Photosynthesizing bacteria release oxygen into the sea Oxygen concentrations increase in the atmosphere. Many new animal species evolve. Single shell organisms increase atmospheric methane concentrations
Many new animal species evolve. Single cell organisms increase atmospheric methane concentrations. Photosynthesis bacteria release oxygen into the sea. Oxygen concentration increases in the atmosphere
Single celled organisms increase atmospheric methane concentration. Oxygen concentrations increase in the atmosphere. Photosynthesis bacteria release oxygen into the sea. Many new animal species evolve
Single-celled organisms increase atmospheric methane concentrations. Photosynthesis bacteria release oxygen into the sea. Oxygen concentrations increase in the atmosphere. Many new animal species evolve

Answer 1

The correct chronological order of events from earliest to latest is:

1. Photosynthesizing bacteria release oxygen into the sea
2. Oxygen concentrations increase in the atmosphere
3. Single-celled organisms increase atmospheric methane concentrations
4. Many new animal species evolve

Thus, the first option reflects the correct order of events:

Photosynthesizing bacteria release oxygen into the sea → Oxygen concentrations increase in the atmosphere → Single-celled organisms increase atmospheric methane concentrations → Many new animal species evolve.
