Q. $C u^{2 +}$ will have the following electronic configuration

$1 s^{2}, 2 s^{2} 2 p^{6}, 3 s^{2} 3 p^{6} 3 d^{10}$

$1 s^{2}, 2 s^{2} 2 p^{6}, 3 s^{2} 3 p^{6} 3 d^{9}, 4 s^{1}$

$1 s^{2}, 2 s^{2} 2 p^{6}, 3 s^{2} 3 p^{6} 3 d^{9}$

$1 s^{2}, 2 s^{2} 2 p^{6}, 3 s^{2} 3 p^{6} 3 d^{10}, 4 s^{1}$

Ground state of $C u^{29} = 1 s^{2} 2 s^{2} 2 p^{6} 3 s^{2} 3 p^{6} 3 p^{10} 4 s^{1}$
$C u^{2 +} = 1 s^{2} 2 s^{2} 2 p^{6} 3 s^{2} 3 p^{6} 3 d^{9}$
