Solution

The correct options are
A $C_{6} H_{5} N_{2}^{+} C l^{-} \to C_{6} H_{5} C l$
D $C_{6} H_{5} N_{2}^{+} I^{-} \to C_{6} H_{5} I$

The Sandmeyer reaction is a chemical reaction used to synthesize aryl halides from aryl diazonium salts using copper salts as reagents or catalysts. It is an example of a radical-nucleophilic aromatic substitution.

Hence, the correct options are $A$ and $D$
