Solution

The correct option is B oxidized
In this reaction, copper is losing oxygen and hydrogen is gaining oxygen. If a substance gains oxygen during a reaction, it is said to be oxidised. If a substance loses oxygen during a reaction, it is said to be reduced. So, in this reaction, hydrogen is getting oxidised while hydrogen is getting is reduced.
