Answer: Option (b) is the correct answer.
Step-by-step explanation:
A carbonated drink is defined as a drink in which carbon dioxide gas is dissolved into a liquid.
For example, in cold drinks like pepsi, coca-cola etc carbon dioxide gas is present into the liquid.
The air we breath contains a mixture of gases like nitrogen, oxygen, etc.
Ice cubes are the solid state of water and there is no presence of gas in an ice cube.
A helium balloon also contains only helium gas and no other gases.
Therefore, we can conclude that out of the given options a carbonated drink is an example of a gas-liquid mixture.
