adding sugar to tea pouring milk on cereal spreading jelly on toast sprinkling cheese on eggs
I gave my students this multiple choice question: A student completes several tasks while making breakfast. During which task does the student make a solution?

Only one answer is correct among these 4 choices:
- adding sugar to tea
- pouring milk on cereal
- spreading jelly on toast
- sprinkling cheese on eggs

Could you tell me which one is correct?
