Solution

The correct option is D $B e^{+ 2} = A l^{+ 2}$
Option (D) is correct.
Order of polarising power between $A l^{+ 3}$ and $B e^{+ 2}$ (both shows digonal relationship) is $B e^{+ 2} = A l^{+ 3}$ .
Polarising power depends on the size of the cation.As the size of beryllium and aluminium are almost same , thus possess same polarising power.
