Answer:
The proper matching is given below.
Explanation:
a Separate molecules by size   size exclusion chromatography
b Separate molecules by charge Ion exchange chromatography
c The stationary phase has a covalently bound group to which a protein in the mobile phase can bind. Â Â Â Â Â Â Â Â Â Affinity chromatography
d uses mobile phase and stationary phase to separate protein Size exclusion chromatography
e The stationary phase contain  cross linked polymers with different pore size
                                 Size exclusion chromatography
f can separate molecules based on protein ligand binding  Affinity chromatography
