Explanation:

The Iranian Parliament authorised the replacement of the national currency, the rial with another basic unit of currency called the toman. The plan is set to effectively cut four zeros from its currency, making each toman worth 10,000 rials under the new system. The Guardian Council, a body of conservative clerics that supervises Parliament, is expected to ratify the law, and then the Central Bank will have two years to implement the change — removing rials from circulation and issuing tomans instead. Iran’s move is to offset the fallout from inflation fueled by U.S. sanctions. Hence statement 3rd is correct.
