Solution

The correct option is D All of these
Silica gel is polar in nature. If we use silica gel as the stationery phase in TLC, we should use some non-polar solvents as a moving or mobile phase, so that separation of the mixture becomes easy and feasible. Hence, all of the above can be used as mobile phase in TLC.
