Logic 2: It was later moved to Delhi by Anangpal Tomar in the 11th century CE.

Logic 3: Its rust-resistant property is due to a specific composition of high phosphorus and low sulfur in the iron.

Conceptual Deep Dive & Logic

"Why is the Mehrauli iron pillar rust-resistant?"

It is rust-resistant due to a unique protective layer formed by its high phosphorus content and specific forging techniques.

Examiner's Mindset & Pro-Tip
