The correct answer is D. It can have elevated concentrations of dissolved substances
Explanation:
Metamorphic processes are different processes and reactions involved in the transformation of rocks, which usually takes place in the crust and the mantle. Metamorphic processes often involve rocks reacting to different factors such as temperature, pressure, and other substances including water. In the case of water, this is an important factor in the metamorphic process because it usually has elevated concentrations of dissolved substances such as fluorine that can trigger or contribute to the transformation of rocks. Also, water can contribute to other factors such as pressure or temperature. Thus, water affects metamorphic processes because "It can have elevated concentrations of dissolved substances".
