Broad range of drugs act against which organisms?

• A. Fungi
• B. Gram positive
• C. Gram negative
• D. Wide variety including Gram positive and Gram negative

Answer: (D)

Broad-range drugs, or broad-spectrum antibiotics, are active against a wide variety of bacteria, including both Gram-positive and Gram-negative groups. That broad coverage is what makes the phrase “wide variety including Gram positive and Gram negative” the best fit. Drugs that target only fungi are antifungals, not antibacterial, and those that act only on Gram-positive or only on Gram-negative bacteria are narrower in scope. Understanding this helps explain why broad-spectrum agents are chosen when the exact organism isn’t yet identified, as they cover multiple potential culprits.
