Answer:

C a chemical has become a different color

Step-by-step explanation:

is it a chemical change when water turns to ice? or to water vapor? no because it can easily change back.

it's not A obviously

I just explained why it's not B

and again it's obviously not D

It's C because once you change the color of something you can most likely not change it back (cake batter, stained glass) making it a chemical change
