What is not true regarding antibiotics?

• A. They can be used for diseases caused by viruses.
• B. They target bacteria.
• C. They can be used for bacterial infections.
• D. They have side effects.

Answer: (A)

The main idea here is that antibiotics are designed to target bacteria, not viruses. Bacteria have features that antibiotics can disrupt—like the cell wall, specific bacterial ribosomes, or enzymes involved in DNA replication. Viruses, on the other hand, don’t carry out those bacterial processes; they hijack the host cell’s machinery to replicate. Because of this fundamental difference, antibiotics don’t kill viruses or stop viral infections. That’s why the statement about using antibiotics for diseases caused by viruses isn’t true. Antibiotics are useful for bacterial infections, and they can cause side effects such as stomach upset or allergic reactions. They should be used appropriately to treat bacterial illnesses and to help prevent antibiotic resistance.
