Pick out the wrong statement about distillation operation

In differential (simple) distillation, the vapour is removed as soon as it is formed without appreciable condensation

Distillation under vacuum is a substitute for steam distillation

In flash (equilibrium) distillation, a definite fraction of liquid is vaporised in such a way that the evolved vapour & residual liquids are in equilibrium with each other

Flash distillation, differential distillation & steam distillation are all continuous distillation processes

When one of the fluids is highly corrosive and has fouling tendency, it should

Flow outside the tube, when the flow is counter-current and inside the tube when the flow is co-current

Flow at a very slow velocity

Perferably flow outside the tube

Preferably flow inside the tube for its easier internal cleaning
