Pick out the wrong statement pertaining to the design of the distillation column.

None of these
If sufficient slot area is not provided, the gas may pass through the skirt clearance
The purpose of the slot is to disperse the gas into the liquid in the form of small bubbles
Generally, a skirt clerance of 0.5" to 1.5' is recommended to prevent plugging of the slots by residue build up
