The electrolytes are: Cu (NO3) 2 NaOH BaSO4 AgBr.

If a substance dissociates into ions, then it is an electrolyte.

You can use the table of solubility of acids and bases in water to determine electrolytes.
In our example, the Cu (NO3) 2 salt and the NaOH base are electrolytes, since they are soluble and readily dissociate.

BaSO4 and AgBr are insoluble salts, they do not dissociate and therefore are not electrolytes.
