Which of these is an example of a solution

A Sand stirred in water

B Sugar stirred in tea

C A glass of water with ice in it

D Oil and vinegar in a salad dressing jar

I have taken this same test and can confirm that the answer is C.

I believe the correct answer from the choices listed above is option B. Sugar stirred in tea is an example of a solution. A solution is a mixture that exhibits homogeneous properties all throughout the mixture. Hope this answers the question. Have a nice day.
