i would go with the third one because you are physically changing the appearance of something. the last one would be a chemical change. the second one is changing light energy into chemical energy. and the first one is basically the same as the second one where it is about changing the elements of a something which is not physical but rather chemical where your converting light energy into chemical energy.
