Solution
The correct option is D Poling
Blister copper contain Cu2O as impurity and is refined by poling process.
In this process, the molten impure metal is stirred with green logs of wood because such a wood liberates hydrocarbon gases (like CH4), and hence, act as a reducing agent to reduce copper oxide to metal.
Option B is correct.
