Correct answer: D. D Herelle
- A. Charles Chamberland
- B. Ivanowski
- C. Twort
- D. D Herelle
Explanation
Felix d'Herelle coined the term bacteriophage for viruses that infect and destroy bacteria. Frederick Twort independently observed bacteriophages earlier, which is why students often confuse him with d'Herelle. Ivanovsky is associated with the discovery of filterable infectious agents later recognized as viruses.

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.
