Question

Choose the correct answer from the options given below:
(A) Magnaporthe is a pathogen on dicot only
(B) Puccinia is a pathogen on monocot only
(C) Ralstonia is a pathogen on dicot and monocot
(D) RNA virus is a pathogen on dicot and monocot only

• A. (A), (B), (C) only
• B. (A), (B), (C), (D)
• C. (B) and (A) only
• D. (C) and (D) only

Hint:

To remember host specificity:
- *Ralstonia solanacearum* is famous for having one of the widest host ranges among plant pathogens, infecting hundreds of species across both monocots and dicots.
- Heteroecious rusts (*Puccinia*) require both a monocot (cereal) and a dicot (alternative host) to complete their macrocyclic life cycle.
