Match Group I (plant disease), Group II (causal organism) and Group III (affected plant) in \textbf{CORRECT combination.}

• A. P-II-a, Q-V-b, R-III-d, S-I-e
• B. P-III-d, Q-V-c, R-II-e, S-IV-f
• C. P-III-d, Q-V-c, R-I-b, S-II-e
• D. P-V-c, Q-I-d, R-VI-b, S-II-e

Hint:

When matching plant diseases with their causal organisms and affected plants, always check the specific organism and the plant it commonly affects based on scientific classification.

Answer 1

The Correct Option is C

Step 1: Analyze the plant diseases and their causative organisms.
- Karnal Bunt (P) is caused by Neovossia indica (III) and affects Rye (d).

- Powdery mildew (S) is caused by Blumeria graminis (II) and affects Wheat (e).

Step 2: Conclusion.
Based on the above analysis, the correct matching is (C) P-III-d, Q-V-c, R-I-b, S-II-e.
