Answer
# Brief Explanations:
The Great Oxidation Event was a major environmental change where oxygen levels in Earth's atmosphere increased significantly. This affected the chemical makeup of the atmosphere. Option A is incorrect as oxygen - iron interaction formed red bands (iron oxides). Option B only focuses on rock bands and not the broader non - living aspects. Option D is about living populations, not non - living things.
# Answer:
C. It changed the chemical makeup of Earth's atmosphere.
