**Core Concept**
Antibiotics are a class of antimicrobial drugs used to treat bacterial infections. They work by inhibiting the growth or killing bacteria, but are ineffective against viral infections and some fungal infections.
**Why the Correct Answer is Right**
Antibiotics are useful in treating bacterial infections by targeting specific cellular processes that are essential for bacterial survival. For example, beta-lactam antibiotics such as penicillin work by inhibiting cell wall synthesis in bacteria, while aminoglycoside antibiotics work by inhibiting protein synthesis. However, antibiotics are not effective against viral infections, such as the common cold or influenza, because viruses do not have the same cellular processes as bacteria.
