The correct Answer is:
C
Lithium and magnesium shows diagonal relationship. Some points of similarity are
(I) polarising power of `Li^(+) and Mg^(+)` are almost same
(II) like Li, Mg decomposes water very slowly.
(III) LiCl and `MgCl_(2)` are deliquescent.
(IV) Like Li, Mg do not form solid bicarbonates.
