Which option correctly matches the solution category with the example?
Answer and explanation
Correct answer: Gas in liquid—soda water
The governing principle is to identify the solute first and the solvent second. Soda water contains carbon dioxide gas dissolved in liquid water, so it is gas in liquid, making B correct. Ethanol in water is liquid in liquid, camphor in nitrogen is solid in gas, and hydrogen in palladium is gas in solid. Thus each distractor reverses or mismatches at least one component state.
