Answer:

iii. ion-exchange chromatography

Explanation:

We have to purify the proteins and column chromatography is used widely for the purification of proteins. Ion-Exchange chromatography is also a type of column chromatography.

When the sugar binding protein X passes through the column, the sugar and  proteins binds together by exchanging ions and coagulated out no matter what the nature of charge on proteins...
