Answer:
The correct answer is A The student is investigating the passive transport of diffusion.
Explanation:

In this question the 10 drops are red coloured food particles that are placed into the beaker, diffuses to all the regions of the beaker untill the concentration of that red colored food particle become same in all the regions to which red colored food particle diffuse.
