The option that best describes hydrolysis is:
carbon dioxide reacting with water to form an acid that dissolves minerals in rock.
However, it's worth noting that hydrolysis itself specifically refers to the reaction of water with minerals, often resulting in the alteration or breakdown of those minerals. The process can include the formation of acids (like carbonic acid from CO2) that enhance the reaction. If you need a more precise definition regarding hydrolysis specifically, it would focus on water reacting chemically with minerals.
