उत्तर
Common salt is obtained from sea-water by the process of evaporation.
Explanation:
Seawater is trapped in shallow pans and left exposed to the sun and wind. Over time, the water absorbs heat and turns into water vapour, leaving behind solid salt crystals. This crude salt is then collected and purified for household use.
