Answer 1

The correct option is (b) Chromatography

The explanation: The methodologies used to remove the excess water present are as follows:

• Use of hydrolases.

• Use of molecular sieves which absorbs water.

• Vacuum distillation, if the organic phase has a high boiling point.

Chromatography is used for separation of a mixture which is dissolved in a fluid called the mobile phase and carrying it through a structure holding another material called the stationary phase. The separation is based on differential partitioning between the mobile and stationary phases.
