The correct Answer is:
To solve the question, we need to evaluate both the assertion and the reason provided. ### Step 1: Analyze the Assertion The assertion states: "Pasteur coined Contagium Vivum Fluidum." - This statement is incorrect. The term "Contagium Vivum Fluidum," which translates to "infectious living fluid," was actually coined by the scientist M.W. Beijerinck, not Pasteur. ### Step 2: Analyze the Reason The reason states: "Pasteur found that virus infected plants of tobacco can cause infection in healthy plants." - This statement is also incorrect. It was M.W. Beijerinck who demonstrated that extracts from virus-infected tobacco plants could infect healthy plants. Pasteur did significant work in microbiology and vaccination but did not make this specific discovery regarding tobacco plants. ### Step 3: Conclusion Since both the assertion and the reason are incorrect, we conclude that the correct answer to the question is: - **Both assertion and reason are false.** ### Final Answer Option D: Both assertion and reason are false. ---
