(D) $1$. For $_{21}Sc$: The atomic number is $21$. The configuration is $[Ar] \, 3d^1 \, 4s^2$,which is correct.$2$. For $_{89}Ac$: The atomic number is $89$. The configuration is $[Rn] \, 5f^0 \, 6d^1 \, 7s^2$,which is correct.$3$. For $_{29}Cu$: The atomic number is $29$. Due to the stability of the fully filled $d$-subshell,the configuration is $[Ar] \, 3d^{10} \, 4s^1$,which is correct.$4$. Since all the given options are correct,the correct answer is $D$.
