Answer:
B. sugar added to water
Explanation:
A solution means a mixture where you can only see one "part" with the naked eye (without microscopes and other equipment). In other words, it is homogeneous, which means everything looks the same. The prefix homo- means same.
When you add sugar to water, the sugar will dissolve into the water. Then, you would not be able to see the sugar, only the clear liquid that looks like water, which is only one "part".
