Final answer:
The drawer of a check is discharged when the holder of the check procures it to be certified, as the bank guarantees payment, removing the drawer's liability.
Step-by-step explanation:
When the holder of a check procures it to be certified, the party that is discharged is the drawer. Certification of a check means that the bank has verified that there are sufficient funds in the drawer's account to cover the check, and it sets aside those funds for payment. Therefore, since the bank guarantees the amount, the drawer is discharged from liability. This means the correct answer is option A. The indorser, if any, is not discharged by this action, and they remain liable until the check is paid.
