Explanation:

To solve this, we analyze each option:

• Option A: Water in metamorphic processes can carry dissolved substances (like ions) which facilitate reactions and element movement, so this is correct.
• Option B: Water actually helps elements move (e.g., via ion transport), so it doesn't stop movement. Eliminate B.
• Option C: Water typically increases the rate of metamorphic reactions (by aiding ion transfer), so C is wrong.
• Option D: Water enables ion transfer between/within minerals (not prevent), so D is wrong.

Answer:

A. It can have elevated concentrations of dissolved substances.
