The correct answer is (d).
M1 is a measure of the money supply that includes currency in circulation and demand deposits. Currency in circulation refers to the physical money that is in the hands of the public, while demand deposits are checking accounts that can be easily withdrawn.
Time deposits are not included in M1 because they are not as liquid as currency and demand deposits. Time deposits are savings accounts that cannot be easily withdrawn, and they typically have a minimum balance requirement.
Currency with the public is included in M1 because it is a form of money that is readily available for spending. Currency is also the most liquid form of money, meaning that it can be easily converted into other forms of money or goods and services.
Demand deposits are included in M1 because they are a form of money that is readily available for spending. Demand deposits are also a relatively liquid form of money, meaning that they can be easily converted into other forms of money or goods and services.
Therefore, the correct answer is (d).
