Final answer:
Checks provide convenient receipts for purchases, which is an advantage in personal and business accounting. They can be stolen, contrary to one of the options, and funds are not immediately available after deposit.
Step-by-step explanation:

While checks can indeed be stolen and are not necessarily more widely accepted than currency, they offer a tangible record of payment that can be useful for personal and business accounting. However, contrary to one of the choices, the funds from a deposited check are not always available for immediate use due to the processing time required by banks.
