(B, C) The electronic configuration of the given ions are as follows:$1$. $Cr^{+3}$ $(Z=24)$: The ground state configuration is $[Ar] 3d^5 4s^1$. After losing $3$ electrons,it becomes $[Ar] 3d^3$.$2$. $Mn^{+2}$ $(Z=25)$: The ground state configuration is $[Ar] 3d^5 4s^2$. After losing $2$ electrons,it becomes $[Ar] 3d^5$. This is a half-filled $d$-orbital configuration.$3$. $Fe^{+3}$ $(Z=26)$: The ground state configuration is $[Ar] 3d^6 4s^2$. After losing $3$ electrons,it becomes $[Ar] 3d^5$. This is a half-filled $d$-orbital configuration.Since both $Mn^{+2}$ and $Fe^{+3}$ show half-filled configurations,and the question asks for which of the following shows half-filled configuration,the option 'All' is technically incorrect as $Cr^{+3}$ does not. However,based on standard multiple-choice patterns,if the question implies 'which of these',and $Mn^{+2}$ and $Fe^{+3}$ are both correct,the most appropriate answer is $B$ and $C$. Given the provided options,if we must choose one,$Mn^{+2}$ and $Fe^{+3}$ are both valid. Assuming the question intended to include both,we select $B$ and $C$ as valid examples.

Which of the following shows half-filled configuration?
