The Correct Option is B
Solution and Explanation
Concept:
Antifungal drugs are grouped by the kind of ring system they contain. The azole antifungals are split mainly into imidazoles (two nitrogen atoms in the ring) and triazoles (three nitrogen atoms).
Step 1:
Ketoconazole has an imidazole ring, which has two nitrogen atoms. So it is classified as an imidazole antifungal.
Step 2:
Triazoles include drugs like fluconazole and itraconazole, which is a different group. Polyenes are drugs like amphotericin B and nystatin. Tetrazole is not the ring in ketoconazole. So the other options are wrong.
Answer: Option (2) — Imidazole.
