Which statement about antibiotics is true?

Which statement about antibiotics is true?

• A. They improve digestion in all species
• B. They are effective against fungi
• C. They are vitamins
• D. They are used to treat bacterial infections

Answer: (D)

Antibiotics are drugs that target bacteria, either killing them or stopping their growth, so they are used to treat bacterial infections. They do not improve digestion in all species, and they are not antifungal agents, which are used to treat fungal infections. They are also not vitamins or nutrient vitamins; vitamins are nutrients the body needs in small amounts, not medicines used to treat infections. Because of this specific action against bacteria and not fungi, viruses, or nutrients, the statement that antibiotics are used to treat bacterial infections is the correct one.
