Which of the following should be used to treat an allergy of the skin?

Using lotions to treat a skin allergy is appropriate because they are designed to moisturize and soothe the skin, which can help alleviate irritation associated with allergic reactions. Lotions often contain soothing ingredients that can reduce inflammation and provide hydration, making them effective for calming allergic skin reactions.

Antibiotics are typically used to treat infections rather than allergies, ointments can sometimes be too heavy for certain allergic reactions, and scrubs are generally used for exfoliation and could potentially irritate sensitive skin. Thus, lotions serve as the best option for providing relief and comfort in cases of skin allergies.
