Final answer:
Currency, traveler's checks, and demand deposits are the 3 deposit items that are available on the same business day of deposit.
Step-by-step explanation:
The 3 deposit items that are available on the same business day of deposit are: currency, traveler's checks, and demand deposits (also known as checking accounts).
Currency refers to coins and bills that circulate in an economy. Traveler's checks are a form of prepaid checks that can be exchanged for local currency. Demand deposits, or checking accounts, allow individuals to withdraw money or make payments through cash withdrawals or checks.
These 3 deposit items are part of M1 money supply, which is measured daily by the Federal Reserve System.
