B. incorrect
C. identify substances that have the measured molecular mass
Explanation:
Since in the question it is mentioned that the Christy who is a forensic scientist and she gave a white powder and identify whether it is a sugar or not when she tested she seen that the molecular mass is different as compared with the sugar
So here it can be concluded that the white powder does not show a sugar that means it is not a sugar so automatically the hypothesis of Christy is wrong. And, the next step is to track the substance that shows the molecular mass i.e. measured
Your answer is C. Both gasoline and litter would need to be physically separated from the water, because neither bonds with the water.
