It is common to elute TLCs using a mixture of solvents since the mixture provides a solution with a polarity between that of the pure liquids. By adjusting the ratio or percentage of each solvent in the solution it is easy to "tune" the polarity of the eluent. Considering this fact, rank the following in increasing polarity. (
