Answer 2

Heyya dear here is ur answer ⤵⤵⤵

If the zinc coating is broken, the " galvanized object remains protected against rusting because zinc is more reactive than iron and hence can be easily oxidized."

Thus when zinc layer breaks down, the zinc continues to react and get oxidized. Hence iron object is protected.
