An 'unauthorized check' is defined as a check that has been written or endorsed without the account holder's consent. This means that someone has attempted to access the account and create a check in the name of the account holder without their approval, which constitutes fraud. The crucial aspect of an unauthorized check is the lack of consent from the account holder, which distinguishes it from other types of checks.

In terms of context, the other options do not reflect the definition of an unauthorized check accurately. For instance, a check approved by the bank does not imply anything about the consent of the account holder; it merely reflects the bank's processing of a legitimate transaction. A check that has been cleared successfully indicates that it has passed through the banking system and settled, without addressing whether it was authorized. Finally, a check that is issued electronically merely describes a method of payment and does not relate to the authorization status of the transaction. Thus, the definition that emphasizes the account holder's lack of consent is the only one that accurately captures what constitutes an unauthorized check.
