Understanding Insecticide Classifications: LIST-I vs LIST-II
This question requires matching specific insecticides listed in LIST-I with their corresponding classifications provided in LIST-II. The classifications involve different types of organophosphate insecticides and organochlorine insecticides.
Matching Insecticides to Their Types
We need to correctly pair each insecticide from LIST-I with its appropriate category from LIST-II:
- LIST-I:
- A. Dichlorvos
- B. Melathion
- C. Parathion
- D. Lindane
- LIST-II:
- I. Type A organophosphate insecticide
- II. Type B organophosphate insecticide
- III. Type C organophosphate insecticide
- IV. Organochlorine Insecticide
Detailed Explanation of Matches
Let's examine each insecticide and its classification based on the provided correct answer:
- Dichlorvos (A): Dichlorvos is recognized as an organophosphate insecticide. In this specific classification context, it is matched with Type A organophosphate insecticide (I).
- Melathion (B): Melathion is another significant organophosphate insecticide. According to the correct pairings, it is classified as Type C organophosphate insecticide (III).
- Parathion (C): Parathion is a well-known organophosphate insecticide widely used in agriculture. The given correct answer places it under the category of Type B organophosphate insecticide (II).
- Lindane (D): Lindane is chemically distinct from organophosphates. It belongs to the class of organochlorine compounds and is identified as an Organochlorine Insecticide (IV).
Correctly Matched Pairs
The correct matching derived from the analysis is presented below:
| LIST-I | LIST-II |
|---|---|
| A. Dichlorvos | I. Type A organophosphate insecticide |
| B. Melathion | III. Type C organophosphate insecticide |
| C. Parathion | II. Type B organophosphate insecticide |
| D. Lindane | IV. Organochlorine Insecticide |
Identifying the Correct Option
Based on the established correct pairings (A-I, B-III, C-II, D-IV), we need to find the option that reflects this combination. Option 5 correctly represents these matches.

Choose the correct answer from the options given below: - Given below are two statements. One labelled as Assertion (A) and the other labelled as Reason (R) :
Assertion (A) : The fundamental goal of a dose - response assessment is to obtain a mathematical relationship between the amount of a toxicant that a human is exposed to and the risk that there will be.
Reason (R) : To apply dose - response data obtained from animal bioassay to humans, a scaling factor must be introduced. Choose the correct answer : - Which of the following statement is incorrect ?
