Which of the following is most suitable for applying as a dilute paste to reduce the burning sensation caused by an ant sting?
Answer and explanation
Correct answer: Baking soda
An ant sting commonly introduces methanoic acid into the skin. Baking soda, sodium hydrogen carbonate, is a mild base; its alkaline nature can neutralise some of the acid and reduce irritation, so option C is the best choice. Lemon juice and vinegar are acidic and could increase irritation. Curd is not the standard neutralising treatment described by this concept.
