What is the most likely reason for this behaviour?

Universal Containers (UC) implemented SSO to a third-party system for their Salesforce users to access the App Launcher. UC enabled “User Provisioning” on the Connected App so that changes to user accounts can be synched between Salesforce and the third party system. However, UC quickly notices that changes to user roles in Salesforce are not getting synched to the third-party system .

What is the most likely reason for this behaviour?
A . User Provisioning for Connected Apps does not support role sync.
B . Required operation(s) was not mapped in User Provisioning Settings.
C . The Approval queue for User Provisioning Requests is unmonitored.
D . Salesforce roles have more than three levels in the role hierarchy.
