Answer 1

• Nothing. All are same, they all are shouting that we are "National level" commodity exchange anc can trade in multiple commodities. (I guess you must be refering Indian commodity exchanges in this question)
• All the three are authorized exchanges where investors can trade in commodities. All three have a national presence and an established electronic trading system. All the three exchanges facilitate trade in multiple commodities ranging from precious metals like gold and silver to raw agricultural products.
