Solution

The correct option is C

Tin is less reactive than Zinc and a nontoxic metal


The explanation for the correct answer

Option C: Tin is less reactive than Zinc and a nontoxic metal

  • Zinc is more reactive than Tin.
  • Tin (Sn) only reacts with very strong acids.
  • However, Zinc can react with simple acids found in food.
  • Hence, in order to prevent food poisoning, the food cans are coated with less reactive metal like Tin.
  • Therefore, the correct option is (C). Food can are coated with Tin and not with Zinc because Tin is less reactive than Zinc and a nontoxic metal.
