Correct answer: D. Penetrating Corrosion
- A. Electrochemical Corrosion
- B. Chemical Corrosion
- C. Corrosion does not occur at all

Explanation
High-copper amalgam still undergoes electrochemical and chemical corrosion, but it largely prevents the penetrating corrosion associated with the tin-mercury gamma-2 phase. Eliminating gamma-2 is the main corrosion-resistance advantage of high-copper amalgam.
