1. Ag2SO4 2. CuF2 3. MgF2 4. CuCl and why?

I think it is MgF2 because mostly compounds of 1 and 2
group are coloured

see CuF2 will have 2 F atoms and Cu in +2 oxidation state.....
hence u can calculate...the config of Cu+2 and u'll get the ansr....
which harsha has posted above.....

I wud add something more...............
THE BASIC THING IS IF YOU HAVE d-orbital not fully-filled in which transition of e- can take place then you will have the salt colored.........
so CuCl is the answer very well explained above........

@panks_01 its not always like that....those transition elements which in their ionic form have fully filled d-orbital will not have colored salts.......
