NEED HELP questlon 2 of 10 When he designed his experiment, Marcos found that he had three small vials of the same size and two slightly larger ones. He did not think that the vials were close enough in size to use them all at once in comparing the properties of the different liquids. How could he solve this problem?

A. Add a few drops of salt to the smaller vials to increase the surface tension of the liquids.

B. Add a few drops of salt to the larger vials to increase the surface tension of the liquids.

C. Use vials that are the same size, and wash and dry them well in between uses.

D. Add more liquid to the larger vials so that they come up to the same height​
