Answer: (C)
Solution
Match each substance with its effect/use:
A. Sulphate → III. Laxative effect: High concentrations of sulfate in water can cause laxative effects (e.g., magnesium sulfate, Epsom salt).
B. Fluoride → II. Bending of bones: Excess fluoride causes fluorosis, leading to skeletal problems including bending and weakening of bones.
C. Nicotine → I. Pesticide: Nicotine is used as an insecticide/pesticide.
D. Sodium arsinite → IV. Herbicide: Sodium arsinite () is used as a herbicide and weedkiller.
Correct matching: A-III, B-II, C-I, D-IV
