Best answer
Right option is (b) False

Explanation: In the manufacturing of stainless steel, both chromium and carbon can be oxidized due to decarburization of molten casting. Carbon oxidation in comparing with chromium oxidation may occur at temperature above 1220 ⁰C in the pure state conditions. But experimentally, carbon oxidation can occur at temperature above 1800 ⁰C than that of chromium.
