What is the latest date Don could submit a NEW Event Request Form to adhere to UnitedHealthcare's rules?

To determine the correct latest date for submitting a NEW Event Request Form in accordance with UnitedHealthcare's rules, it is essential to consider the organization's deadlines for event submissions. Typically, these deadlines are set to ensure adequate processing time for approvals and arrangements.

In this context, the earliest deadline mentioned in the choices indicates that the submission must occur well before the event date, often several weeks in advance. Therefore, submitting the request by October 14 is consistent with best practices for advance planning, ensuring that UnitedHealthcare has sufficient time to review and approve the request.

Submission after that date might not allow for adequate processing time, which could lead to potential complications or a lack of approval for the event. Thus, October 14 represents the latest date by which a NEW Event Request Form should be submitted to comply with UnitedHealthcare's rules.
