The correct answer would be moleculer change because physical change is literally the exact thing that the question is telling us that we need to have the out of the answer (composition) and chemical change is like (for example): If we have an egg and we crack it and the yoke comes out, and that would have to be composition because we have to crack the egg. And we can't change somethings molecules. So that would be the answer (moleculer change).
