Question

acknowledgement certificate iron pillar​

Answer 1

Explanation:

The iron pillar of Delhi is a structure 23 feet 8 inches (7.2 metres) high with 16 inches diameter that was constructed by Chandragupta II (reigned c. 375-415 CE), and now stands in the Qutb complex at Mehrauli in Delhi, India.[1][2] It is famous for the rust-resistant composition of the metals used in its construction. The pillar weighs over six tonnes (13,228 lb) and is thought to have been erected elsewhere, perhaps outside the Udayagiri Caves,[3] and moved to its present location early in the [Delhi Sultanate].
