Artificial way of causing rainfall to reduce air pollution makes use of

Option (A) is correct because silver iodide and potassium iodide possess crystalline structures nearly identical to natural ice, allowing them to act as efficient nuclei for moisture to condense and fall as rain. Option (B) is the most tempting distractor, but silver nitrate is incorrect because it is highly water-soluble and lacks the specific hexagonal lattice required to mimic ice crystals effectively. This question tests the core concept of **Cloud Seeding**, a weather modification technique used to induce precipitation and wash out atmospheric pollutants.
