Which of the following is NOT a type of unmedicated ointment?

Explanation:
The main idea is distinguishing ointments that moisturize or protect skin without delivering an active drug from those that do carry an active ingredient. Emollients soften and hydrate the skin by supplying lubricating lipids. Protectants create a barrier to shield irritated skin and prevent moisture loss. Occlusives are a subset of emollients that form a water-tight film to further reduce water loss and support the skin’s barrier. Antibiotics, however, are active drug ingredients designed to treat infection, so when an ointment contains an antibiotic it is a medicated preparation, not an unmedicated one.
