Correct answer: C

  1. Identify each substance and its known effect/use

    We match the items in List I with the most appropriate description in List II.

    (A) Sulphate

    Sulphate salts such as magnesium sulphate and sodium sulphate are known to produce a laxative effect.

    Hence, (A) Sulphate→(III) Laxative effect\text{(A) Sulphate} \to \text{(III) Laxative effect}(A) Sulphate→(III) Laxative effect

    (B) Fluoride

    Excess fluoride in drinking water causes fluorosis, which affects bones and teeth. One important effect is bending/deformation of bones.

    Hence, (B) Fluoride→(II) Bending of bones\text{(B) Fluoride} \to \text{(II) Bending of bones}(B) Fluoride→(II) Bending of bones

    (C) Nicotine

    Nicotine is obtained from tobacco and has been used as a natural insecticide/pesticide.

    Hence, (C) Nicotine→(I) Pesticide\text{(C) Nicotine} \to \text{(I) Pesticide}(C) Nicotine→(I) Pesticide

    (D) Sodium arsinite

    Sodium arsinite is used as a herbicide.

    Hence, (D) Sodium arsinite→(IV) Herbicide\text{(D) Sodium arsinite} \to \text{(IV) Herbicide}(D) Sodium arsinite→(IV) Herbicide

  2. Final matching

    Therefore, the correct matching is: A−III,  B−II,  C−I,  D−IVA-III,\; B-II,\; C-I,\; D-IVA−III,B−II,C−I,D−IV

  3. Compare with options

    This corresponds to Option C.

  4. Comparison with stored answer

    Stored correct answer = C.

    Our derived answer = C.

    So, they agree.
