Answer:
The correct option is;
C. The volume and mass do not change
Step-by-step explanation:
We note that a piece of paper usually does not compress when load is applied on it.
Therefore, when a piece of paper is crumbled, the volume does not change as the paper only becomes folded thereby, reducing its surface area with a corresponding increase in thickness
The mass of the paper does not change as in the process of the paper being crumbled, the matter and therefore, the mass remains constant.
