Which of the following is NOT one of the three primary corrosion control strategies?

Corrosion inhibitors are not one of the primary ways we prevent corrosion. The main approaches are to choose materials that resist corrosion, apply a protective coating to keep the metal separate from the environment, and use cathodic protection to shift the metal’s electrochemical potential so it doesn’t oxidize. Inhibitors, while useful, are chemicals added to a fluid or system to slow corrosion and are considered a supplementary method rather than one of the core strategies. So the option that lists corrosion inhibitors is the one that doesn’t belong to the three primary strategies. The other choices—material selection, protective coatings, and cathodic protection—are the primary strategies because they either reduce exposure, create a barrier, or alter the electrochemical conditions to minimize corrosion.
