The correct response is:
**It reacted with iron in rocks to produce iron oxide.**
The production of oxygen by photosynthesis led to the Great Oxidation Event, during which free oxygen released into the atmosphere reacted with iron dissolved in the oceans, forming iron oxide (rust) and precipitating out of the water, which significantly impacted the geological and atmospheric conditions of the Earth.
