CaCl2 and NaCl r ionic bcoz in each of them one is a metal and one is a nonmetal which bond by loosing & gaining electrons to get complete outer shells

For a compound to be ionic, it has to be composed of elements which differ significantly in electronegativity values.
therefore metals and nonmetals will mostly satisfy this rule
therefore:
A= is not ionic
B=is not ionic
C=is ionic
D= is not ionic
E=is ionic
as a rule of thumb
(all metals in group one and two form ionic compounds with halogens like Cl,Br,I etc)
