(C) $K_3[Cu(CN)_4]$: $Cu$ is in $+1$ oxidation state $(3d^{10})$,so it has no unpaired electrons,making it diamagnetic and colourless.$(NH_4)_2[TiCl_6]$: $Ti$ is in $+4$ oxidation state $(3d^0)$,so it has no unpaired electrons,making it diamagnetic and colourless.$VOSO_4$: $V$ is in $+4$ oxidation state $(3d^1)$,so it has one unpaired electron,making it paramagnetic and coloured.$K_2Cr_2O_7$: $Cr$ is in $+6$ oxidation state $(3d^0)$,so it has no unpaired electrons. It is diamagnetic,but appears coloured due to ligand-to-metal charge transfer $(LMCT)$.

Among the following,the compound that is both paramagnetic and coloured is
