The answer is Redox reaction as well as displacement reaction because both reduction and oxidation takes place. And O2 gets displaced from Cu to H2. Hope it helps!!!

Answer:
CuO + H2 with heat = Cu + H2O
This reaction represents,
b. Redox reaction as well as displacement reaction
Explanation:
Reaction: CuO + H2 with heat = Cu + H2O
Case 1 :
- In this reaction when CuO is heated with H2, displacement of O occurs and binds with H2 and forms H2O because copper has lower reactivity with oxygen.
- So, It is called Displacement reaction.
Case 2:
- Also oxidation states of reacting substances are changing by transferring of electrons.
- Oxidation number of Cu is changed from +2 to 0 in CuO and oxidation number of O2 is changed from 0 to +1 in H2O.
- So, it is called Redox reaction also.
Hence, it is proved that the above reaction represents a redox reaction as well as a displacement reaction.
