Answer 1

Correct choice is (b) Desalting

The best I can explain: The following methodologies are used to extract an enzyme from the upper phase of aqueous 2 phase system:

* Addition of salts

* Addition of a polymer

* Generating a new biphasic system

Desalting cannot be used to extract an enzyme from the upper phase.
