Answer 1

Answer: (c) Zinc is more reactive then tin. Which may react with food items and make it unfit for health.

Answer 2

I think you've made a mistake while reading the question.

The question is " Food cans are coated with tin and NOT with zinc."

Zinc is more reactive than tin. This means that it will react with the food stuff and form toxic substances.

Since tin is less reactive than zinc, the rate of reaction will obviously, be slower as compared to when the container is made of zinc.
