Final answer:
A license will lapse if the licensee does not renew it on time, does not meet continuing education requirements, or does not update their contact information. Complying with all regulations is necessary to maintain, not lapse, a license.
Step-by-step explanation:
A license might lapse due to several reasons. The student has asked which of the following would cause a license to lapse: A. Not renewing the license on time, B. Failing to meet continuing education requirements, C. Complying with all regulations and rules, D. Not updating contact information. Options A, B, and D are correct since they represent actions that if not addressed would lead to a lapse in the license. However, option C is incorrect because complying with regulations and rules would not cause a license to lapse; in fact, it is required to maintain the license.
Therefore, a license will lapse if the licensee fails to renew it on time, fails to meet continuing education requirements, or fails to update their contact information, as these are critical components of maintaining a valid license in most professions.
