B Correct answer
Explanation

Distilled water is the purest form of water because it is produced by boiling water into steam and then condensing it back into liquid, leaving behind virtually all impurities, dissolved salts, and contaminants. Sea water contains high salt content, tap water may contain minerals and treatment chemicals, and bottled water like Bisleri undergoes purification but still contains some dissolved minerals compared to completely pure distilled water.
