Your lab partner tested the solubility of a sugar from a packet and sugar cubes in two different liquids in order to determine if both sugars are the same substance. Your partner only collected the results for the test tubes A, B, and F. If you collected the results for C D and E, what would you predict your results would be if both samples were the same substance A. C would be soluble, D would be soluble, and E would be soluble

B. C would be not soluble, D would be not soluble, and E would be soluble

C. C would be not soluble, D would be soluble, and E would be soluble.

D. C would be soluble, D would not be soluble, and E would be not soluble
