4. Why is the pillar resistant to corrosion?

Due to a passive protective film

Due to high amounts of phosphorus in the metal

Do to the alternate wetting and drying under atmospheric conditions

All above

The pillar is resistant to corrosion due to a combination of factors. Firstly, it has a passive protective film that forms on its surface, which acts as a barrier against corrosion. Additionally, the high amounts of phosphorus in the metal contribute to its corrosion resistance. Lastly, the alternate wetting and drying under atmospheric conditions also helps to prevent corrosion. Overall, all of these factors work together to make the pillar resistant to corrosion.
