The answer is D. Copper sulfate spreads out through water as a result of diffusion.

i just had this one on USA testprep

Answer: Option D

Explanation:

The experiment was performed in order to see what happens to the crystals of copper sulfate when it is put into water.

The observation that was seen at the end of the experiment is that the copper sulfate crystals gets dissolved in the water.

This is because of diffusion in which the particles moved from one place to another. The concentrated copper sulfate got diffused in water and the color of whole water changed.
