Which medication is an antifungal?

• A. Diphenhydramine
• B. Cetirizine
• C. Carprofen
• D. Miconzol 1%

Answer: (D)

Understanding drug classes helps identify the right choice for a fungal infection. Antifungals specifically attack fungi, for example by disrupting their cell membranes. Miconazole is a topical antifungal; it works against fungal skin infections and is commonly used as a 1% topical preparation in veterinary care.

The other medications shown are not antifungals: diphenhydramine and cetirizine are antihistamines used to treat allergic symptoms, and carprofen is a nonsteroidal anti-inflammatory drug for pain and inflammation. Since the question asks for an antifungal, the option containing miconazole is the correct choice.
