According to United Healthcare policy, when must a marketing/sales event be reported?

The correct answer highlights the requirement for prior advertising of a marketing or sales event, specifically that it must occur at least 7 days before the event takes place. This guideline ensures that there is ample time for the target audience to be informed about and prepared for the event, thereby increasing participation and effectiveness.

This advance notice is crucial for compliance with United Healthcare's policies aimed at maintaining transparency and fostering informed choices among potential participants. It allows the organization to adhere to regulatory standards that govern marketing activities in healthcare, thereby helping to establish trust and credibility with consumers.

In contrast, the other options suggest timelines either after the event or do not provide sufficient lead time for effective outreach, which does not align with the intent of promoting accessibility and awareness for consumers prior to a marketing event.
