The correct response is **rust deposits**.

The increase in atmospheric oxygen during the Great Oxidation Event led to the oxidation of iron, resulting in the formation of banded iron formations and rust deposits. This evidence correlates with the diversification of animal life, as higher oxygen levels allowed for more complex organisms to evolve.
