Explanation:
An allergic reaction occurs when our immune system misinterprets a harmless substance into a harmful antigen and initiate an over-expressed immune response against it. Some of these allergic substances are pollen, molds, insect stings, etc.

It can affect the nose, skin, lung, stomach lining, etc. Therefore the correct answer is an allergic reaction.
