Detailed Solution

Both Assertion and Reason are true, and the reason is the correct explanation of the assertion.
Assertion: Zinc metal (Zn) is more reactive than tin (Sn). Hence it reacts with organic compounds to form other compounds harmful to humans. Food cans are coated with tin but not with zinc because zinc may react with organic compounds present in food material.
Reason: Zinc comes before tin in the electrochemical chain of reactions. This means that zinc is more reactive than tin. Due to this, zinc can react with food. But tin cannons react with food. Due to this, food can be preserved in tin containers but if you keep food in a zinc container, then food will get spoiled. so the assertion is correct and reason is the correct explanation of the assertion.
