The correct option is (c) Chromium depleted zone near the grain boundary
Explanation: !8-8 stainless steel is susceptible to intergranular corrosion due to sensitization in the temperature of 950 to 1450°F. At this stage, chromium reacts with carbon near the grain boundary and results in the formation of the chromium depleted zone. This chromium depleted zone is prone to intergranular corrosion.
