Solution & Step-by-step Explanation

Zinc has a more negative electrode potential than Iron, which means it is more easily oxidized. In galvanized iron, Zinc acts as a sacrificial anode, providing electrons in preference to Iron. Only when all the Zinc has been oxidized does the Iron start to rust. Both assertion and reason are true and the reason correctly explains the protective mechanism.
