Solution

Correct answer is Anode
Electrode which is connected to positive terminal of battery is anode.
Electrode which is connected to negative terminal of battery is cathode.
Negative ions migrated to the positively charged anode.
These anions donate excess electron and get oxidised and form neutral atoms.
Therefore oxidising electrode is anode.
