The correct Answer is:
To solve the question of identifying the correct match of the scientist and their discovery, we will analyze each option step by step. ### Step 1: Analyze Option (a) **Statement**: T.H. Diener: An agent consisting of abnormally folded protein. **Analysis**: - The correct name of the scientist is T.O. Diener, who discovered viroids, which are small infectious RNA molecules. - Viroids do not have a protein coat, so this statement is incorrect. ### Step 2: Analyze Option (b) **Statement**: W.M. Stanley: Crystals from viruses contain proteins. **Analysis**: - W.M. Stanley is known for his work on the Tobacco Mosaic Virus (TMV) and was the first to crystallize a virus. - He demonstrated that viruses can exist in a crystalline form and contain proteins. - This statement is correct. ### Step 3: Analyze Option (c) **Statement**: M.W. Beijernick: Recognised TMV. **Analysis**: - M.W. Beijernick is known for his work on the Tobacco Mosaic Virus (TMV) but he did not specifically recognize it in the same way as Stanley did. - He coined the term "virus" and described the infectious nature of TMV, but he did not crystallize it. - Therefore, this statement is incorrect. ### Step 4: Analyze Option (d) **Statement**: Ivanowsky: Contagium vivum fluidum. **Analysis**: - The term "contagium vivum fluidum" was actually coined by M.W. Beijernick, not Ivanowsky. - Ivanowsky was the first to demonstrate that the causative agent of TMV could pass through a filter that retained bacteria, but he did not use this term. - Thus, this statement is also incorrect. ### Conclusion Based on the analysis, the only correct match is: **(b) W.M. Stanley: Crystals from viruses contain proteins.** ### Final Answer The correct match of the scientist and their discovery is: **(b) W.M. Stanley: Crystals from viruses contain proteins.** ---
