Solution

Oxidising agent
Any substance which is capable of oxidising other substances is called oxidising agents.
It is capable of accepting electron which is lost during oxidation is called oxidising agents.
${CuSO}_{4} (aq) + Zn (s) \to {ZnSO}_{4}_{} (aq) + Cu (s)$
Copper ions undergo reduction and zinc get oxidised
Oxidation number of oxidising agents decreases during a chemical reaction.
Hence copper sulphate is the oxidising agent and zinc is the reducing agent
