Correct option is A
Explanation:
Let’s match each solar appliance to its correct use:
· (A) Solar Oven → (IV) Cooking
· A solar oven uses sunlight to cook food directly through thermal energy.
· (B) Solar Kiln → (III) Drying products
· Solar kilns are used to dry agricultural or wooden products using solar heat.
· (C) Solar Still → (I) Provide fresh potable water
· A solar still distills water by evaporating and condensing it, removing salts and impurities.
· (D) Solar Thermal Collector → (II) Generate Electricity
· These collectors concentrate solar heat, often used in solar thermal power plants to drive turbines and produce electricity.
Information Booster:
· Solar ovens are simple, portable devices used especially in off-grid cooking.
· Solar kilns are widely used in wood seasoning and post-harvest processing.
· Solar stills are ideal for small-scale water purification in remote or arid areas.
· Solar thermal collectors differ from photovoltaic panels (which convert sunlight directly to electricity).
Additional Information:
· Other options mismatch functions, e.g., assigning cooking to a thermal collector or electricity generation to a still.
· Only Option (1) correctly pairs all devices with their intended purpose.
