Match List-I with List-II. List-I A. Sulphate B. Fluoride C. Nicotine D. Sodium arsenite List-II I. Pesticide II. Bending of bones III. Laxative effect IV. Herbicide Choose the correct match from the options below.

1. A-II, B-III, C-IV, D-I
2. A-IV, B-III, C-II, D-I
3. A-III, B-II, C-I, D-IV
4. A-III, B-II, C-IV, D-I

Correct answer: A-III, B-II, C-I, D-IV

Solution

Sulphate in water gives a laxative effect, excess fluoride causes bone deformities (fluorosis), nicotine is a natural pesticide, and sodium arsenite is used as a herbicide, giving A-III, B-II, C-I, D-IV.
