The answer would be "wood burning" or option B. Chemical change is when a element get's turned into another element. Many people mistaken chemical change, and physical change but psychical change would be this: if you cut a piece of wood in half that would be a physical change because it's still wood but it's smaller. But if you burn wood into ash it would be a chemical change that's because it's no longer wood it's ash.
Also, it wouldn't be option A because that's still water but in gas for which is water vapor which is a physical change. It's also not option C because glass being broken is also a physical change it's still glass but it's smaller. It's also not option D because it's also a physical change, it's still water but in a different form. It wouldn't be option E because it's a physical change it's being molded into liquid iron which means it's still iron but in a different form. Basically all of the other options are examples of a physical change.
Hope this helps!
