Which option has both the type and example correct?
Answer and explanation
Correct answer: Solid in liquid solution—salt in water
The governing concept is classification by the physical states of solute and solvent. In salt water, salt is a solid solute and water is a liquid solvent, so it is a solid-in-liquid solution. Brass is a solid alloy, not a liquid-in-gas example, while soda water contains a gas dissolved in a liquid. Therefore only option A correctly matches both the type and its example.
