D. It can have elevated concentrations of dissolved substances.
Explanation:
Water in a metamorphic process can cause elevated concentrations of dissolved substances which in turn increases the rate of the metamorphic process.
- Metamorphism is a change in the mineral composition of rock in the presence of temperature, pressure and water.
- Water increases the rate of metamorphic processes because they dissolve substances.
- Minerals in a solution reacts faster than the ones in solid state.
- This lowers the activation energy for driving metamorphic transformation of minerals from one form to another.
