Question

Given below are two statements, one is labelled as Assertion (A) and other labelled as Reason (R). 
• [Assertion (A):] Biotrophs can be easily cultured in artificial medium. 
• [Reason (R):] Biotrophs lost their independent growth due to co-evolution with the host. 
In light of the above statements, choose the most appropriate answer from the options given below: 
 

• A. Both (A) and (R) are correct and (R) is the correct explanation of (A).
• B. Both (A) and (R) are correct but (R) is NOT the correct explanation of (A).
• C. (A) is correct but (R) is not correct.
• D. (A) is not correct but (R) is correct.

Hint:

To remember pathogen nutrition styles:
- Biotrophs: Require living cells (e.g., rusts, powdery mildews). Cannot be grown on artificial media.
- Necrotrophs: Kill cells and feed on dead tissue (e.g., Alternaria). Easy to culture.

Answer 1

The Correct Option is D
