Match the compounds given in column-I with the oxidation state of cobalt present in it (given in column-Il) and assign the correct code.

S.No.	Column-I (Complexes)	S.No.	Column-II  (Oxidation state of Co)
(P)	$\left[\mathrm{Co}\left(\mathrm{NCS}\right){\left({\mathrm{NH}}_3\right)}_5\right]{\mathrm{SO}}_3$	(1)	+4
(Q)	$\left[\mathrm{Co}{\left({\mathrm{NH}}_3\right)}_4{\mathrm{Cl}}_2\right]{\mathrm{SO}}_4$	(2)	0
(R)	${\mathrm{Na}}_4\left[\mathrm{Co}{\left({\mathrm{S}}_2{\mathrm{O}}_3\right)}_3\right]$	(3)	+1
(S)	$\left[{\mathrm{Co}}_2(\mathrm{CO}{)}_8\right]$	(4)	+2
		(5)	+3
