Solution

The correct option is A zinc is more reactive
Food cans are generally coated with tin rather than zinc because zinc is more reactive than tin. Food and beverage cans have to preserve the taste and nutritional values of their filling for up to several years. Zinc will react with the food items and make it unfit to eat. Hence, zinc is not preferred for the manufacture of food cans.
