Which of the following could prevent the Start Review button from appearing for a reviewer? (Select All That Apply)

The correct choice relates to settings and configurations that affect the visibility and functionality of the Start Review button for reviewers. When the classification index is inactive, it means that the system does not recognize or utilize the classification framework necessary for initiating a review process. Without an active classification index, the system fails to present relevant options, such as the Start Review button, which is conditional upon the classification being operational.

This condition highlights the importance of maintaining active and properly configured settings within the project management system to ensure all necessary functions are available to users.

In contrast, the other options do not inherently lead to the absence of the Start Review button. For instance, while permissions and the selection status on the Project Home Tab are crucial for user experience, they do not directly relate to the functionality tied to the classification index, leaving it as the primary reason for the button's unavailability.
