Short Answer D

If you see any change at all, you know something is moving where it was not moving before.

The smell of turkey (or perfume) can only happen if atoms are moving from the kitchen to your nose. There is no other transport mechanism.

A change of color is most often associated with chemical reactions, but it need not be that alone. The molecules can just be moving around and lend their color to (in this case) white milk.

Well this one is a little tough. You can't see anything happening if you put (say) a 1/2 teaspoon of sugar in an 8 oz cup. But you know something has happened to the water when you taste it. Taste is one of our senses and when we detect something like sweetness we know that something sweet has been add to what we drink. Only molecular motion can account for that.
