Identify the incorrect statement regarding distillation processes:

Explanation

Option A is correct because vacuum distillation serves as an alternative to steam distillation. Option B accurately describes simple distillation where vapor is quickly removed without condensation. Option C correctly explains flash distillation where vapor and liquid coexist in equilibrium. Option D is false since flash distillation and differential distillation are typically batch or semi-batch processes, not continuous like steam distillation.
