Ans3 is:
M0: currency (notes and coins) in circulation and in bank vaults. M0 is usually called the monetary base - the base from which other forms of money (like checking deposits, listed below) are created - and is traditionally the most liquid measure of the money supply
M1: currency in circulation + checkable deposits (checking deposits, officially called demand deposits, and other deposits that work like checking deposits) + traveler's checks. M1 represents the assets that strictly conform to the definition of money: assets that can be used to pay for a good or service or to repay debt. Although checks linked to checking deposits are gradually becoming less popular, debit cards linked to these deposits are becoming more popular. Like checks, debit cards, as a means to complete a transaction through their links to checkable deposits, can also be considered as a form of money
M2: M1 + savings deposits, time deposits less than $100,000 and money market deposit accounts for individuals. M2 represents money and "close substitutes" for money. [9] M2 is a key economic indicator used to forecast inflation
M3: M2 + large time deposits, institutional money-market funds, short-term repurchase agreements, along with other larger liquid assets. M3 is no longer measured by the US central bank
