• A. Vaccines.
• B. Antibiotics.
• C. Antivirals.
• D. Antifungals.

Answer: (B)

Medicines that cure bacterial infections by killing the bacteria inside the body are called antibiotics. They work by targeting differences between bacterial cells and human cells—such as cell wall formation or essential bacterial enzymes—so they can kill the bacteria or stop them from multiplying, allowing the immune system to clear the infection. Some antibiotics are bactericidal (they kill bacteria) and others are bacteriostatic (they stop growth), but both are used to treat bacterial infections. Vaccines prevent infections by training the immune system, antivirals treat viral infections, and antifungals treat fungal infections.
