Cu 2+:[ Ar ] 3 d9 4 s0 Cr 3+:[ Ar ] 3 d3 4 s0 Sc +:[ Ar ] 3 d1 4 s1 All are coloured and paramagnetic due to presence

Q. The set having ions which are coloured and paramagnetic both is -

$C u^{2 +}, C r^{3 +}, S c^{+}$

$C u^{2 +}, Z n^{2 +}, M n^{4 +}$

$S c^{3 +}, V^{5 +}, T i^{4 +}$

$N i^{2 +}, M n^{7 +}, H g^{2 +}$

$C u^{2 +} : [A r] 3 d^{9} 4 s^{0}$
$C r^{3 +} : [A r] 3 d^{3} 4 s^{0}$
$S c^{+} : [A r] 3 d^{1} 4 s^{1}$
All are coloured and paramagnetic due to presence
