“Carbon steels and low alloy steels, such as 9 Cr, have poor oxidation resistance at temperatures above 1000°F (540°C), rapidly losing thickness.”
“Stainless steels with higher Cr and Ni content (like 310) have superior oxidation resistance.”
Thus, 9 Cr steel will corrode fastest at 1350°F, making option D correct.
