Answer 1

Hint:The iron pillar is a 23 feet 8 inches high structure with 16 inches diameter that was designed by Chandragupta II. It is well-known for its rust-resistant composition of the metals used in its construction.

Complete answer:
-The Iron pillar is situated in Quwwat-ul Mosque at Mehrauli in Delhi, India.

-It weighs more than 6 tons and is made of 98% wrought iron. Being exposed to dust and air of Delhi for about 1600 years now, the pillar has not caught rust yet.
- According to an IIT Kanpur metallurgist, Dr Ramamurthy Balasubramaniam, the pillar was made by a technique known as ‘forge welding’ and the iron was not entirely pure but included small portions of slag, a byproduct of the smelting process. This helped it to develop a ‘passive protective film’ and it retards the corrosion process.
-The outstanding city of Delhi is blessed with several gardens, monuments and botanical houses which are the reason for which Delhi is famous for.
-Even some places are enlisted under UNESCO's World Heritage Sites. There are three places in Delhi which come under this list, that is, Humayun's tomb and Qutub Minar.

Hence, the correct answer is option A.
