Which statement is true regarding the mailing of refund checks?

The statement that refund checks are mailed after processing is true because it reflects the standard procedure for handling refunds. Typically, when a request for a refund is submitted, it has to go through a processing phase where the request is verified, approved, and then the check is prepared. This ensures that all necessary documentation and checks are in place to prevent errors or fraudulent claims. Only after this thorough processing is the check mailed out to the customer.

The other options suggest that refunds could be prepared immediately, cannot be processed, or are electronically transferred, which do not align with the usual protocol for refund handling. It is essential to ensure that a refund is properly processed before it is issued, as this helps maintain accuracy and integrity in the financial operations of the organization.
