Question:
Match List-I with List-II
List-I (Agent) List-II (Class) (A) Fenvalerate (I) Organophosphate (B) Malathion (II) Carbamate (C) Paraquat (III) Pyrethroid (D) Propoxur (IV) Bipyridinium compound
Match List-I with List-II
| List-I (Agent) | List-II (Class) |
|---|---|
| (A) Fenvalerate | (I) Organophosphate |
| (B) Malathion | (II) Carbamate |
| (C) Paraquat | (III) Pyrethroid |
| (D) Propoxur | (IV) Bipyridinium compound |
Show Hint
- Paraquat is a classic bipyridinium herbicide (C-IV).
- Malathion is a classic organophosphate insecticide (B-I).
Matching these two is sufficient to find the correct option.
- Malathion is a classic organophosphate insecticide (B-I).
Matching these two is sufficient to find the correct option.

Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Understanding the Concept:
Veterinary toxicology classifies pesticides and herbicides into groups based on their chemical structures and mechanism of action.
Detailed Explanation:
Let us match each chemical agent with its corresponding chemical class:
- (A) Fenvalerate: This is a synthetic (III) pyrethroid insecticide. It works by keeping sodium channels open in neuronal membranes.
- (B) Malathion: This is a widely used (I) organophosphate insecticide. It inhibits the enzyme acetylcholinesterase, leading to cholinergic overstimulation.
- (C) Paraquat: A highly toxic non-selective herbicide. It belongs to the (IV) bipyridinium compound class and causes severe pulmonary fibrosis by generating reactive oxygen species.
- (D) Propoxur: A pesticide belonging to the (II) carbamate class, which also acts as a reversible inhibitor of acetylcholinesterase.
This yields the matched sequence:
\[ \text{(A) - (III), (B) - (I), (C) - (IV), (D) - (II)} \]
Step 2: Final Answer:
The correct matching sequence corresponds to Option (B).
