Which item is explicitly cited as a cause of corrosion?

• A. Improper heat treatment at manufacturer
• B. Moisture and industrial chemicals
• C. Proper packaging and handling
• D. Good housekeeping

Answer: (B)

Moisture provides the electrolyte that enables electrochemical corrosion, and when industrial chemicals are present they can attack the metal surface or remove protective coatings, accelerating the corrosion process. In aircraft maintenance, humidity, rain, wash water, leaks, and exposure to cleaners or solvents create the conditions that lead to corrosion, so this combination is a clearly cited cause. The other items are typically preventive measures (packaging, handling, housekeeping) or potential material issues that aren’t described as the explicit, common cause in standard references.
