The probable answer here is letter C.

Letter A can't be the answer since when we talk about color differences there is a "difference involve. So it is observing the magnitude of the change in color.

Letter B can't be the answer since when we involve colorimetry, there is a corresponding values to these readings. This is actually a quantitative test.

Letter C is the answer since, we are just observing if there is a certain color appears after the reaction takes place.
