Answer

Virus is discovered by D.J. Ivanowsky but name was given by Pasteur, so D is correct option

Answer

Explanation:

The correct answer is option B - D.J. Ivanowski.

Discovery of Viruses:
- In the late 1800s, scientists were studying tobacco plants affected by a disease called tobacco mosaic disease.
- It was known that the disease was caused by an infectious agent that could pass through filters designed to remove bacteria.
- In 1892, a Russian botanist named D.J. Ivanowski conducted an experiment to investigate the nature of the infectious agent.
- Ivanowski extracted sap from infected tobacco plants and passed it through a porcelain filter that was known to retain bacteria.
- Surprisingly, even after filtration, the sap still retained the ability to cause the disease when applied to healthy plants.
- Ivanowski concluded that there must be an invisible, filterable agent present in the sap that was responsible for causing the disease.

The Term 'Virus':
- The term 'virus' was later coined by another scientist named Martinus Beijerinck in 1898.
- Beijerinck further studied the infectious agent and proposed that it was different from bacteria, but he was unable to determine its exact nature or structure.
- He named the infectious agent 'virus,' which is derived from the Latin word 'virus' meaning 'poison' or 'slimy liquid.'

Contributions of Other Scientists:
- While Ivanowski and Beijerinck made significant contributions to the discovery and initial understanding of viruses, it was other scientists who further elucidated their nature and structure.
- One such scientist was Wendell M. Stanley, an American biochemist, who is credited with the first isolation and crystallization of a virus.
- In 1935, Stanley successfully isolated the tobacco mosaic virus and demonstrated that it was composed of protein and nucleic acid.
- This discovery provided concrete evidence that viruses are distinct biological entities separate from bacteria and other microorganisms.
- It also paved the way for further investigations into the structure, replication, and classification of viruses.

Conclusion:
- In conclusion, while D.J. Ivanowski was the scientist who conducted the experiment and discovered the filterable infectious agent, it was Martinus Beijerinck who coined the term 'virus' to describe this agent. However, it was Wendell M. Stanley who made significant contributions to the understanding and characterization of viruses through his isolation and analysis of the tobacco mosaic virus.
