Correctly matched items match(es) among the following is (are)

	Column I (Pairs of amino acids)	Column II (distinguishing test)
I	Proline and Histidine	${\text{NaNO}}_{\text{2}}/\text{Con}.\text{HCl}$
II	Serine and Glycine	Ceric ammonium nitrate solution
III	Tryptophan and Tyrosine	Neutral ferric chloride solution
IV	Lysine and Glutamic acid	${\text{NaHCO}}_{\text{3}}$

Proline does not have primary amino group while histidine has. With NaNO2/HCl, histidine gives effervescence of nitrogen.
Serine has an alcohol group and hence gives red colouration with ceric ammonium nitrate.
Tyrosine has phenolic group and hence would give characteristic colouration with FeCl3.
As both Lysine and glutamic acids both have acidic groups, they both would evolve CO2 with NaHCO3 and hence can’t be differentiated.
