Question

Processed foods are stored in _____ cans.

• A. iron-coated tin
• B. copper-coated aluminium
• C. tin-coated iron
• D. zinc-coated iron

Answer 1

The correct option is C tin-coated iron

Iron gets corroded by humidity and moisture over time. So, electroplating it with tin increases its resistance towards corrosion. Thus, instead of pure iron cans, tin-coated iron cans are used.
