Best answer
Right option is (a) True

To elaborate: Numerous failures of 18-8 stainless steel have occurred in the temperature range of 950 to 1450°F. When these steels are heated in the range of 950 to 1450°F they become sensitized or susceptible to intergranular corrosion due to the depletion of chromium at the grain boundary.
