Match the compounds given in Column I with the oxidation state of coba

1.	Match the compounds given in Column I with the oxidation state of cobalt present in it (given in Column II) and assign the correct code. {:(,"Column I (Compound)",,"Column I (Oxidation state of Co)"),("A".,[Co(NCS)(NH_(3))_(5)](SO_(3)),1.,+4),("B".,[Co(NH_(3))_(4)Cl_(2)]SO_(4),2.,0),("C".,Na_(4)[Co(S_(2)O_(3))_(3)],3.,+1),("D".,[Co_(2)(CO)_(8)],4.,+2),(,,5.,+3):}
