$\mathrm{Cu}^{2+}:[\mathrm{Ar}] 3 \mathrm{~d}^{9} 4 \mathrm{~s}^{0}$

$\mathrm{Cr}^{3+}:[\mathrm{Ar}] 3 \mathrm{~d}^{3} 4 \mathrm{~s}^{0}$

$\mathrm{Sc}^{+}:[\mathrm{Ar}] 3 \mathrm{~d}^{1} 4 \mathrm{~s}^{1}$

All are coloured and paramagnetic due to presence of unpaired $\mathrm{e}^{-}$

The set having ions which are coloured and paramagnetic both is :
