Which of the following actions can lead to the expiration of a license?

The action that can lead to the expiration of a license is failing to submit a complete application for renewal. Licensing authorities require a complete renewal application to ensure that all necessary information is provided for review. If an application is incomplete, it cannot be processed, and this can result in the license being deemed expired if the renewal deadline passes without proper submission.

Timely payment of renewal fees typically ensures that the license is maintained in good standing, so it would not lead to expiration. Similarly, receiving a license in multiple states is generally permissible, as licenses are managed individually by each state's regulatory body. Completing continuing education credits after expiration does not rectify the situation of an expired license; the credits must be completed before expiration for them to count towards maintaining the license.
