The correct choice highlights that a lawyer can terminate a retainer when there is a material change in circumstances or client misconduct. This reflects the ethical obligation lawyers have to ensure they can effectively represent their clients. A material change in circumstances may affect the lawyer's ability to provide competent representation, such as changes in the client's situation that fundamentally alter the nature of the case. Additionally, if a client engages in misconduct—such as lying or failing to uphold their responsibilities—this can sever the professional relationship because it undermines the trust and essential communication necessary for effective legal representation.

In contrast, a client requesting to change lawyers is not a valid reason for termination from the lawyer's perspective, as the lawyer does not have the right to refuse a client's decision to seek representation elsewhere. While failure to pay fees can be a reason for a lawyer to withdraw from representing a client, it is typically a process that requires careful consideration and adherence to specific legal and ethical guidelines, making this option not universally applicable. The reason of being "too busy" does not justify termination of retainers as lawyers are expected to manage their workload appropriately to honor existing commitments.
