Answer:
b) Zinc with dil.HCl
Explanation:
A Single Displacement reaction takes place between HCl and Zinc as Zinc is higher in metal reactivity series than Hydrogen. Zinc easily loses electrons and gets oxidized to Zn2+ and H+ from HCl get reduced to give Hydrogen gas.
As Copper is lower in reactivity series it does not react with dil. HCl to release Hydrogen gas
