Which statement best describes NSF (non-sufficient funds)?

• A. A bank transfers funds between accounts.
• B. A check is returned because the account has enough funds.
• C. A bank returns a check because there were insufficient funds in the account.
• D. Funds are fully available for withdrawal

Answer: (C)

Non-sufficient funds means there aren’t enough money available in the payer’s account to cover a check. When a check is presented and the balance is insufficient, the bank does not pay the check and instead returns it unpaid (a bounced check) and may charge a returned-item fee. This description exactly matches the idea that a bank returns a check because there were insufficient funds in the account. The other statements describe different banking actions or outcomes—transferring funds between accounts, a check being returned when funds exist, or funds being fully available for withdrawal—which do not reflect NSF.
