Pick out the wrong statement pertaining to the design of the bubble cap tray of a distillation column to give stable operation and even vapour distribution.

None of these

Tendency towards stable operation is increased by increasing the skirt clearance of the caps, lowering the rate of liquid flow per unit plate width or increasing the spacing between the caps

The dimensionless ratio of liquid gradient to pressure drop head caused by the bubble cap assembly should be less than 0.4

The pressure drop due to the caps & slots and the static submergence should be as high as practicable for reasonable operation

High pressure fluid in a shell and tube heat exchanger should preferably be routed through the

Shell side, if the flow is counter-current and tube side if the flow is co-current

Shell side for smaller total pressure drop

Shell side for large overall heat transfer co-efficient

Tubes to avoid the expansion of high pressure shell construction
