(D) The electronic configuration of $Cr (Z=24)$ is $[Ar] 3d^5 4s^1$. This configuration is adopted because half-filled $d$-orbitals $(d^5)$ provide extra stability. In the $3d$ subshell,there are $5$ electrons,each occupying one of the $5$ $d$-orbitals singly. Therefore,the number of unpaired electrons in the $d$-orbitals is $5$.
