The Correct Option is B
Solution and Explanation
Correct answer: anode
Explanation:
In the process of corrosion of iron (like rusting), the spot where iron corrodes acts as the anode. At the anode, iron loses electrons and gets oxidized to form iron ions:
\( \text{Fe} \rightarrow \text{Fe}^{2+} + 2e^- \)
These electrons travel to another spot (the cathode), where they reduce oxygen in the presence of water. Thus, the corroding spot is the anode.
