Which of the following presents the correct sequence of increasing basic nature of given oxides?

$\begin{matrix} (A) K_2O < Na_2O < Al_2O_3 < MgO \\ (B) Al_2O_3 < MgO < Na_2O < K_2O \\ (C) MgO < K_2O < Al_2O_3 < Na_2O \\ (D) MgO < K_2O < Na_2O < Al_2O_3 \end{matrix}$

The increasing order of cations is: $ Al^{3+} < Mg^{2+} < Na^{+} < K^+$
The basic nature of oxides increases with increase in the size of cation.
Therefore, the order that is the correct sequence for increasing basic size of oxides is $(B) Al_2O_3 < MgO < Na_2O < K_2O $
