Answer and explanation
Correct answer: A paste of baking soda
An ant sting contains methanoic acid (formic acid). Baking soda is a mild base, which helps neutralise this acid and can reduce the burning sensation. In contrast, vinegar, lemon juice, and orange juice are acidic, so they are not suitable choices for an acidic sting.
