Reena has arranged the following experimental set-up to observe the reactivity of different metals.

In which beaker(s) will there be no reaction?

In test tube II copper can not displace $H_2$  from HCl

In a test tube, IV copper cannot displace Al from $A{l}_2{\left(S{O}_4\right)}_3$ .

In both cases, copper is less reactive than $H_{2}andAl$
