Solution

The correct options are
A Only $C u F_{2}$ is ionic
B Both $C u C l_{2}$ and $C u B r_{2}$ are covalent
As the electronegativity of halogens (F,Cl.Br.I) is more the compounds fomed by these elements are ionic but Cu is also having near EN value compared to halogens,so as we move from top to bottom in a group the ionic charecter of the compounds decreases and covalent charecter increases
Hence options A &B are correct.
