A case may be cancelled for which of the following reasons?

The correct answer is that a case may be canceled if it was created in error. When a case is established based on incorrect or misleading information, continuing to pursue it would be unnecessary and could waste resources. This situation often arises when there is a misunderstanding of the issue at hand or if the case does not meet the criteria for further investigation.

In contrast, while resolving the issue would typically lead to case closure rather than cancellation, a member being unresponsive usually prompts additional follow-up efforts to engage that individual rather than cancellation. Similarly, the need for more information may lead to an extension of the case or additional inquiries, rather than cancellation outright. Therefore, recognizing when a case was erroneously created is crucial for maintaining the integrity of case management and ensuring effective use of resources.
