All viruses are generally resistant to which of the following antibiotics?
Correct answer: C. Both A and B
- A. Penicillin
- B. Streptomycin
- C. Both A and B
- D. None
Explanation
Antibiotics are not effective against viral infections like colds, influenza (flu), most sore throats, bronchitis, and many sinus and ear infections. Antibiotics cannot kill viruses because viruses have different structures and replicate in a different way than bacteria. Both, penicillin and streptomycin are antibiotics and hence are not effective in treating viral infections.

About Viruses
Viruses are acellular infectious particles made of genetic material enclosed by a protein capsid, sometimes with a lipid envelope. Their replication depends on a host cell and may follow lytic or lysogenic cycles, so viral structure and reproduction differ fundamentally from those of cellular organisms such as bacteria.
