Correct answer
AA and C only

Step-by-step explanation

(A) Both LiCl & MgCl2 have covalent character so soluble in ethanol.

(C) LiF have low solubility due to high lattice energy.

So these two statements are correct. And other two statements are wrong. 

Since,

(B) Li and Mg do not form superoxide

(D) Li2O is least soluble in water than other alkali metal oxides
