The reactivity series can help to understand the feasibility of the reaction. As per reactivity series the copper ion is present below hydrogen so the reaction in option d cannot take place.
Reactivity series is a list of metals which are arranged in decreasing order of the reactivity and according to this series, the reaction can be predicted.
As in substitution reaction only those metal can replace the other that is having higher reactivity.
In the given reactions, the reaction between hydrochloric acid and copper cannot take place as copper stands below hydrogen so having less reactivity, due to this it will not be able to displace hydrogen from the reaction.
Thus, the correct option is d.
