  1. The electrode made from metal X has positive polarity.
  2. Electrode Y is the anode.
  3. The flow of electrons is from Y to X.
  4. The reaction at electrode X is an oxidation reaction.

A
Electrode Y is the anode.
B
The reaction at electrode X is an oxidation reaction.
C
The flow of electrons is from Y to X.
D
The electrode made from metal X has positive polarity.
Solution
Verified by Toppr

Oxidation occurs at the electrode X which is the anode and it has negative polarity.
Anode: XX+2+2e

Cathode: Y3++3eY

Here, the electron is flowing from X to Y.

Option D is correct.
