A wasp sting contains a basic substance. Which substance can be useful to reduce the pain?

Answer and explanation

Correct answer: Vinegar

Under the stated school-level assumption, a wasp sting is basic in nature. Vinegar contains acetic acid and is a mild acid, so it can theoretically neutralise part of the basic effect; hence option A is the intended answer. Baking soda, slaked lime, and sodium hydroxide are basic or alkaline substances and would not provide the required acid–base neutralisation. Actual stings should be managed carefully, especially if allergic symptoms appear.
