D Correct answer

Lead is commonly used for containers holding strong acids because it forms an insoluble protective layer of lead sulfate on contact with sulfuric acid, preventing further reaction. Platinum is also acid-resistant but prohibitively expensive. Copper and brass readily react with acids.
