Correct Answer: Zinc
Explanation
Given data
- Process: Galvanizing iron (or steel).
- Task: Identify the metal used.
Concept/Approach Galvanizing is the process of coating iron/steel with zinc to provide sacrificial (cathodic) protection against corrosion.
Reasoning • Zinc forms a protective layer and corrodes preferentially, shielding the base metal. • Tin/Chromium are used in other coatings; lead is not used for modern corrosion protection here.
Final Answer Zinc
