Which option allows access to sheets regardless of user permission levels?

The option that allows access to sheets regardless of user permission levels is user-assigned sheets. User-assigned sheets are specifically designed to be accessible by the users assigned to them, regardless of their overall permission levels in the system. This provides a flexible approach to data management and access control, enabling users to view and interact with necessary data without being restricted by broader permission settings that might apply to their roles.

In contrast, sub-level customization, level assigned sheets, and sheet access control involve restrictions or specific assignments that take user permissions into account. Sub-level customization pertains to tailoring sheets at various organizational levels, while level assigned sheets grant access based on specified levels of user hierarchy. Sheet access control sets the permissions governing who can view or edit sheets based on defined roles, ensuring that users only interact with data they are authorized to access. Thus, these options do not provide the same unrestricted access as user-assigned sheets.
