Expert Answer:

Copper< Iron< Zinc
As iron is more reactive than copper so when iron is added to copper sulphate iron displaces copper and iron sulphate is formed.
When zinc reacts with iron sulphate zinc sulphate is formed because Zinc is more reactive than Iron.
Thus in a displacement reaction more reactive element displaces a less reactive element from its compound.
