Which type of substance is most suitable for relief from nettle leaf sting?

Answer and explanation

Correct answer: Mild basic substance

The governing concept is neutralisation of an acidic irritant. Nettle hairs can inject an irritating substance with an acidic effect, so a mild basic material is the suitable opposite treatment in this school-level context. It can reduce the acidity without adding another strong irritant. Therefore option A is correct; a strong acid would worsen irritation, while neutral salt powder or sugar solution does not provide the needed neutralising action.
