Match the properties given in List-$I$ with the metals given in List-$II$:

List-$I$ (Property)	List-$II$ (Metal)
$A$. Element with maximum second ionization enthalpy	$i$. $Co$
$B$. Element with maximum third ionization enthalpy	$ii$. $Cr$
$C$. $M$ in $M(CO)_6$	$iii$. $Cu$
$D$. Element with maximum enthalpy of atomization	$iv$. $Zn$
	$v$. $Ni$

(A-III, B-IV, C-II, D-I) $A \rightarrow iii$ ($Cu$ has a stable $d^{10}$ configuration after losing one electron,making the second ionization energy very high).
$B \rightarrow iv$ ($Zn$ has a stable $d^{10}$ configuration; removing the third electron from the $d$-orbital requires very high energy).
$C \rightarrow ii$ ($Cr(CO)_6$ is a stable metal carbonyl complex).
$D \rightarrow i$ ($Co$ has a high enthalpy of atomization due to strong metallic bonding in the $3d$ series).
