The Correct Option is A
Solution and Explanation
Chromium in chromyl chloride (CrO$_2$Cl$_2$):
Oxidation state of Cr is +6.
Electronic configuration: Cr$^{6+}$ = [Ar] 3d$^0$ 4s$^0$, meaning there are zero d-electrons.
Manganese in Mn (VII):
Oxidation state of Mn is +7.
Electronic configuration: Mn$^{7+}$ = [Ar] 3d$^0$ 4s$^0$, also zero d-electrons.
Thus, the number of d-electrons is the same for Cr in CrO$_2$Cl$_2$ and Mn in Mn (VII).
