Best answer
The correct answer is (b) True

The best explanation: Stainless steels containing small quantities of platinum passivates more readily in the presence of oxygen, ferric salts, and other oxidizing agents. It is due to the resultant mixed potential of an alloy that reaches a passive region quickly.
