उत्तर
Bee sting contains an acidic liquid.
Explanation:
When a honeybee stings, it injects an acidic venom known as apitoxin into the skin. This liquid contains methanoic acid (also commonly called formic acid) along with various proteins and enzymes. The presence of this acid lowers the pH at the sting site, triggering an inflammatory immune response that results in immediate pain, redness, and a burning sensation.
