Answer:
The correct answer is option A) "cause iron in ocean water and terrestrial rocks to rust (oxidize)".
Explanation:
During ancient times, the reproduction success of plants and cyanobacterias led to the accumulation of oxygen gas in the atmosphere. One early consequence of this accumulation was the oxidation of the iron in ocean water and terrestrial rocks. This phenomenon is the cause of banded iron formations, which formed in seawater and sank to the ocean bed.
