\nThe correct match is A-4, B-1, C-2, D-3. This option correctly pairs each noble gas with one of its common or significant uses listed.
\n<\/section>\n
\n– Argon is widely used as an inert filling gas in incandescent light bulbs (tungsten filament lamps) to prevent the oxidation of the filament and reduce its evaporation, thereby increasing the bulb’s lifespan (List II – 4).
\n– Neon is famously used in “neon signs” for advertising displays, producing a characteristic red-orange glow when an electric current is passed through it (List II – 1).
\n– Krypton is used in various lighting applications, including some high-efficiency fluorescent lamps, halogen lamps, and is also used in some airport lighting systems and blended into other high-intensity discharge lamps (List II – 2 is a plausible use, although Xenon is more primary).
\n– Xenon is used in high-intensity discharge lamps such as those found in cinema projectors, high-end car headlights, airport landing lights, lighthouses (List II – 2), and in photographic flash lamps\/guns (List II – 3).
\n<\/section>\n
\nBased on typical primary uses, A-4, B-1, C-3, D-2 would be the most accurate. However, examining the options provided, Option D matches A-4, B-1, C-2, and D-3. Matches A-4, B-1, and D-3 are correct and common uses. While Krypton (C) is not the primary gas for airport landing lights (which is usually Xenon), it is sometimes used in specific systems or blends. Xenon (D) is also a primary gas for photographer’s flash guns. Given the options, D provides the best set of matches, correctly pairing Argon with tungsten filaments, Neon with advertising displays, and Xenon with flash guns, leaving Krypton with a plausible secondary use in airport lighting.
