Correct Answer - C
Metallic character decreases across the period in the sequence as Na,Mg,Al and increases down the group in the sequence as Na,K, As metallic character of the element attached to the oxygen atom increases, the basic character of the oxides increases`:.` the increasing correct order of basic nature is `Al_2O_3ltMgOltNa_2OltK_2O`
