The correct answer is: VOSO4
K2Cr2O7 contains Cr+6(3d0) which is diamagnetic but coloured due to charge transfer spectra.

(NH4)2[TiCl6] contains Ti4+(3d0), which is diamagnetic and colourless.

VOSO4 contains V4+(3d1), which is paramagnetic and coloured.

K3[Cu(CN)4] contains Cu+(3d10), which is diamagnetic and colourless.
